http://paulicio.us/lastfm/ This website will make you a wallpaper out of your most listened to albums on last fm. I think it's pretty cool, and would share it. Here's one of mine, actual pic comes out wallpaper size
I used to use something like this that made a new wallpaper every time you rebooted to computer. My only ******* was that a lot of bootlegs I own are not on Last.fm so have no cover art. Therefore it just appears as a grey square.
But here is mine anyway...
I'm at a loss for why Duran Duran, Bob Dylan and Alphabeat are in there. I hardly ever listen to them, although my Morrissey obsession is very evident.
