If you like music and you haven’t yet got Spotify, wake up.

Spotify is probably the best music application on the planet. It effortlessly streams every bit of music you could possibly want almost instantly, onto your PC. And, if you don’t mind the odd 20 second ad every so often, it’s free. Nothing to pay for all the music you can eat.
A premium service without the ads is available for a monthly subscription.

The downside? You can’t save the music, well not easily and certainly not legally. Spotify uses P2P technology to stream Ogg Vorbis files between users in a similar fashion to BitTorrent. But it’s fast. It’s faster than accessing your stored music in iTunes for example.

And now with the release of libspotify, the company’s API, Spotify could be coming to all manner of other devices. X Boxes, PlayStations, Mobile Phones, Slingboxes, any device capable of streaming can have access to Spotify’s massive music catalogue.

It’s still not legally available in the USA and many other countries, but expect that to change in the future. And any applications built with libspotify will only be available to premium users.
