Haven't really used last.fm for long. But so far this is what I've got. If I had started using it a lot sooner, my top 5 would be a lot different. Hell, most of the artists on there, I barely listen to. They were completely random "Yeah.. kinda feel like this" listens. That said, the only one in it's proper place would probably be NIN. The others would be either higher or lower depending on the group, and some wouldn't even be on this list if I started scrobbling sooner.
