With a seemingly ever-growing number of streaming music services available via the Web and dedicated mobile and tablet apps, choosing the one that best fits your need is an increasingly difficult task.There are lots of options out there, but here are some of the biggest and most notable that are worth checking out.

Spotify

Spotify is one of the best-known music services available, and as such it has a 20 million strong catalogue of tracks available to listen to – it also means there’s a thriving hub of third-party apps too, like the BBC’s Playlister service among many other, with which to extend your listening.

Pandora

Although Pandora is still only available to users in the US, Australia and New Zealand, it’s a veritable granddaddy of online music streaming, but walks a different line to Spotify. Rather than providing tracks on-demand, Pandora users pick an song and let it create a radio station of similar and related music. Thankfully, and as you might expect given its the primary function, this actually works pretty well and keeps recommendations sensible.

For a yearly payment of $36 or a monthly payment of $3.99, Pandora listeners can, however, upgrade to a Pandora One account, which removes all the advertising, and provides access to the service through the standalone Pandora One Desktop app.

Google Play Music All Access

OK, so it has an unwieldy and cumbersome name that we wish Google would change,  and we’ve already given you a pretty deep dive into Google’s music service, but here are several good reasons it deserves consideration in your short list. Currently, there’s a 20,000 track limit on the number of songs you can upload, but this should be enough for a modest music collection.

iTunes Radio

iTunes Radio is obviously, by its very nature of being tied to the largest digital music store, a big player in this list. Offering access from a range of [mostly Apple] devices, iTunes Radio can be used on your iPhone, iPad, iPod touch, Mac, PC, or Apple TV and allows seamless syncing of playlists between them. Like Amazon and Google’s music services, Apple also offers users the option of storing all your locally stored music in iCloud via the iTunes Match service, so you can play it back from any compatible device. To use this feature, you’ll need a premium subscription to iTunes Match costing $24.99 per year.

Deezer

The French company Deezer has been offering music streaming since way back in 2006, although back then it was called Blogmusik. It became a fully fledged business in August 2007.
With many years under its belt already, Deezer is now a mature service with a catalogue of 30 million tracks available for playback. Like the others, at its most basic it offers playlists, music discovery, favorites and integrated social features but it also offers a wide range of different mobile clients including iOS, Android, Windows Phone 7 and BlackBerry. It’s also available on Mac/PCs too, as well as via a dedicated Windows 8 app.

Users that sign up for a free trial of Deezer Premium+ via Facebook are given 15 days to test out the service, before needing to enter card details to carry on using it. Happily, it’ll work in a lot of different countries too, a full list can be found here.

Xbox Music

Xbox Music is Microsoft’s music streaming service that ties together its desktop, gaming, mobile and tablet devices for true multi-platform access, and a replacement for Zune.
It only launched last summer, but it’s already had a makeover for Windows 8.1 and launched on iOS, Android and via a Web player. Naturally, it’s available on Xbox consoles too.

SoundCloud

If you’re looking for a huge repository of music, but one that also lets you upload your own mixes and tracks too, then you’re probably looking for SoundCloud. Primarily intended platform for people to share their own musical creations and mixes, as it has grown in popularity and size, big artists and labels have also signed up, allowing for some of their music to be available through the platform.
SoundCloud offers three pricing tiers:

• Free – Offers two upload hours, 100 downloads, unlimited playlists and access to some stats, like number of plays, downloads, comments and favorites of tracks.
• Pro (€3 per month/€29 per year) – Allows four hours of uploads, access to posting tracks in ‘Quiet Mode’ (allowing you to control comments) and Spotlight (allowing you to pin up to five tracks to the top of your profile to receive more attention). It also includes more detailed stats, with reports on who is playing your tracks and where they’re located.
• Pro Unlimited (€9 per month/€99 per year) – Allows you to upload unlimited single sound file sizes up to 2GB each and within an upload time limit of 30 hours per week.

Grooveshark

Grooveshark is an online music streaming service for playing back individual tracks, artists or albums since back in 2007. The free tier allows ad-supported listening of tracks across a wide range of genres, but it’s really the hassle-free listening and good selection of electronic dance music that scored it a place on this list.

Slacker Radio

Slacker is another radio-style streaming service that’s available across a range of platforms, but unlike, say, Pandora, listeners aren’t restricted to only being able to listen to radio stations.

Sony Music Unlimited

Sony’s music streaming service, like many others, touts a catalog of more than 25 million tracks (“from indies to superstars”) available to play on demand, however, it’s a little different to some of the options here, in that there’s no free streaming plan available. Instead, to entice you to dip a toe into the water, there is a free 30 day trial so you can take it for a test run before deciding to carry on with monthly payments, or not. If you do decide to go ahead and pay for it, the service has two tiers: an Access Plan and a Premium Plan. It’s probably also worth mentioning that at the time of writing, there’s also a 3-month offer for $3/£3.

The Access Plan is the cheaper of the two — $4.99/£4.99/€4.99 — and allows users to access premium Channels, chart listings and editorial playlists curated by the team. Naturally, it also includes unfettered streaming access to the entire catalogue of tracks, or there’s the option to download playlists to your library for offline access – but only up to a limit of 1,000 tracks.

Mixcloud

Mixcloud touts itself as the place for long form audio. In real terms, this means that it’s a great repository for DJ mixes, radio shows, podcasts and any other longer audio formats. The company says that the average length of an upload on its platform is in excess of 40 minutes, and that the average listener stays tuned in for more than 20 minutes, and its long form format means it’s great at just running unattended in the background for hours at a time.

Rdio

Rdio is an ad-free music subscription service that allows users to listen to music on-demand, as well as to stream pre-made stations and playlists of tracks created by other users. Like many of the others, Rdio claims to have that magic 20 million song catalog and offers mobile access for iOS, Android, Windows Phone and BlackBerry devices (via a Web app). Although you’ll need to pay a monthly subscription fee for access from a mobile.

For $4.99/£4.99 per month, you can get access to unlimited streaming on the Web, shown above. Increasing this to $9.99/£9.99 broadens access to include mobile devices (Windows Phone shown below) and streaming via devices like a Roku media player. There’s also a family plan which includes two (by default, although more can be added) unlimited subscriptions starting from $17.99/£17.99 per month.

TuneIn Radio

TuneIn Radio is a little different to the other radio streaming services in this list as it focuses on acting as a hub and player for commercially available radio shows. In total, there are more than 100,000 live stations available, and more than 2 million podcasts. There is actually a chargeable app for iOS (currently $0.99, but usually $6.99) and Android ($6.99) that allow users to record live radio, but still won’t get you out of listening to those adverts. There are also free apps for Android and iOS too. It’s also available for Windows Phone, BlackBerry, some Roku players, through some Internet TVs – and even directly in some cars.

Myspace (Music)

MySpace might seem like an odd one in this list, but since it relaunched, it has re-angled itself as a music and video platform, rather than as a social network.

Beats Music

Beats Music is easily the newest service on this list, so new in fact that it hasn’t even quite started up yet anywhere, but it will on January 21. However, only for users in the US – although further expansion is to be expected, judging from the signup page for people outside the States.

Amazon

Amazon is clearly the elephant in the room when it comes to this, as it doesn’t offer a music streaming service. Yet. However, we’d be surprised if it didn’t offer one in the future.

Round up

As you can see, there are plenty of online streaming options available, with some being more suited to radio listening and others focusing purely on providing individual tracks and albums on-demand.
Most of those included in this list offer an algorithm or human curation aspect to discovery of new music, but you’ll likely need to spend some time using any of them before it accurately learns what you like.
