Today/Yesterday the Spotify Mobile application was announced. There are apps for both iPhone and the Android platforms.
They do require you to have a premium account which will set you back £10 a month.
At first it does seem to be quite a lot but it does give you as much music as you want from thousands of labels.
I'd wanted to go premium for a while now but just to get rid of advertisements that I didn't really mind to begin with just wasn't worth it for me but the release of the iPhone app changed that. I'm planning to use Spotify for all my music as I can have offline playlists when I don't have internet access.
