that should keep u entertained for a while! Now go and MySpace all these bands and see if you like.

If you go with similar artists and you're into melodeath, stick "In Flames" in the search and you'll be given a slew of some great melodeath artists.
I always find Thrash Tag radio to be pretty fun as well.

thanks so far...

Avantasia
