Lastfm

Realise I'm probably months, if not years, behind with this one but lastfm is undoubtably the best website on the internet. So much so that I deleted my Facebook account as I know I will have no time for it from now on.

Takes a short while to get the hang of it but once you do it is so good. The wealth of music available is unbelievable and I would argue that it's better for hearing new bands than MySpace, providing you have some prior knowledge of the group.

I predict worldwide domination.
