Been available in the US for a while, now available in the UK (£21.99) a year.
Basic idea is that it scans your iTunes library - matches up all your songs to those in it's 20 million song database and keeps these in 'the cloud'. Any songs it can't match up it uploads.
You can download a high quality version of the songs it 'matches'.
I signed up yesterday - there are clearly some major teething problems, and I'm not sure I like the way it works on your phone.
There are 9000 songs in my itunes library, it 'matched' about 6500. Bizarrely for quite a lot of albums it matched some of the songs in the album, and I had to upload a few others.
Anyone else signed up - anyone else had problems?
