Does anyone use Spotify?

Does anyone use Spotify? Ill try to explain it for those who dont know, couse its such a cool program which in my opionon everybody should have!:)

Spotify is a new music service where you can listen to music legally over the internet. It all boils down to Spotify has an agreement with some the worlds major record labels for their music to be offered by the program.

To use Spotify you download a program which looks like iTunes. Then you can search on artist and you`ll find their music and albums which you can listen to.
I use the free version of the program, which you only can do if you have got an invite. Its paid by advertising which you will hear after like every 10th song. But theres also a Premium version. This costs like 9 dollars a month and this is ad-free!

So, those of you who uses Spotify, what do you think?I think its a great programe! It benefits both you and the artists. You can listen to free music and the artists earn an amount of money for each of their tracks beeing listen to.
