Spotify is freeware, currently in private beta, which allows you to stream thousands of songs to your desktop for free. It really is how they say, Instant, simple and free.
The desktop program runs like your normal media player, however instead of using your own library you just search a artist or track into the search bar and you will see a list of match’s. Once you found a song you want click on it and almost instantly it will begin as if you had it on your computer.
It achieves this using P2P technology which allows it to run seamlessly, with hardly any wait.
It currently runs on Windows and Mac OS X, there are plans of a iPhone/iPod Touch version in the future which would be great considering how vast the library is using this service.
The software is fully legal and even though it uses the P2P protocol, it’s not illegal as some people would make you believe.

If you want to try out this amazing service leave a comment on this post and the first 5 comments will receive an invite to the private beta.
