Does anyone else think this is a problem in modern metal? It seems like the vast majority of bands stick within 20bpm +/- of a given tempo. You almost never get an album that has fast songs/mid paced songs/slow songs like, say, Heaven and Hell or Piece of Mind.
Agree? Disagree? Personally I think it is one of the worst aspects of modern metal.
It's certainly one of the biggest shortcomings of my own compositions. :\
