Free online music

Yesterday my brother sent me the link to Deezer, a website that streams the songs you want.Most common songs are available, and since it's a French website, many French songs are available. The service is completely legal and available all around the world. I wonder how they managed to do that with actually less limitations than Pandora that i cannot legally listen to from Switzerland.
The widget on the right side of this blog let's you export a player based on one of your playlists. It is also possible to embed a single-song player, really cool to blog about a song. I will probably blog my favorite songs on here.
Thank you Deezer ! You saved space on my hard drive :)
