>>>Soulfly makes dumb music. Something like this is not even subjective.
Are you sure you didn't just try out a couple of bad songs from thier first CD and make a blanket generalization?
I used to think the same, and gave them another chance, and they really do a good job of writing good music to head band too. Helps that I like variety though - they do a good job of changing styles and pace while maintaining their metalness.
The first 5 songs off the Prophecy are just brutal - I don't see how anyone can listen to them and not head bang.
SlipKnoT influenced a lot of young musicians, with the mix of heavy riffs, aggressive lyrics and very fast drumming, they made the late 90's a better place to be for lovers of metal music.
Iron Maiden and Motorhead still carry on the original old-school metal ideal
Static-X have a very unique style, and so do Mushroomhead and Fear Factory have a mix of different styles.
