I give you Epica
Yes! YES! YES!
The human voice can be the best instrument in the band. One of the reasons I like foreign language music is that the language fades into the music and adds to the other instruments.
German should not sound this good. The language adds to the music instead of distracts.
For those of you who demand English but don't want to listen to old people music. Jane Monheit is a phenomenal presence live.
Then you have one of my favorite female voices of all time
Autotune took the inherent beauty and character of the human voice and turned it into a suburban strip mall of mediocrity.
