Actually the very non-70’s Symphonic Metal is more to my taste.
Lyrics are a waste of time.
Melody and musical skill are everything.
Combining a Metal band, a first class opera capable soprano and occasionally a full symphony backup, can make for some very impressive music.
Try Nightwish (with Tarja), Without Temptation or Epica and you will get the idea.
Within Temptation has a nice beat but it’s still too much music. Lyrics are lost or buried. It’s hard to like a song the first time its heard. 7-’s music certainly has stood the test.
