Although I've been using Audioscrobbler for a while, I hadn't tried their sister site Last.fm until last Friday. This site uses their calculation of your musical 'neighbours' to choose other music you might like. This can then be streamed to you at a reasonable 128kb, giving similar quality to most MP3 files. In my case it through in a few new artists to me, e.g. Mogwai, but also old favourites like ELO. Had a good sing along to that :)

If I eventually sort out my Paypal account I'll gift them some money.
