I know this is offtopic, but I'll throw it out here anyway. My Last.fm account is 3 or 4 years old. I was 16 then, I'm 20 now. My tastes today are radically different from what they were 4 years ago. 4 years ago I used to listen to KoRn, Marilyn Manson and Eminem, and nothing much besides. Predictably enough, they were the top 3 artists in my Last.fm charts for a long time. Now my tastes have not only changed, they've become more varied. Some of the artists I listen to now have pushed my old favorites down the charts, but the old favorites still appear the top 10, and Marilyn Manson is still #1.
Sadly, Last.fm insists on listing heavy metal and rap artists as my top recommendations. I'd kill for a music discovery service that could take my changing tasted into account.
You can always browse the "similar artists" section on individual artist's pages. There's a "similar songs" feature as well, but I've found it to be fairly weak.
