I have a pretty wide range of music that I like to listen to and play (I play violin). But for the most part that doesn't incorporate a lot of big record label pop, which along with "major label" country, is probably the most afflicted with high-tech manipulation of the recordings. You never hear that stuff in classical or jazz music, and almost never in metal or prog. And perhaps surprisingly, almost never (except as a deliberate special effect) in the insane Japanese alt-idol* world or in art-pop (think: Kate Bush, Bjork, Oomori Seiko...).

Heh...just imagine hearing pitch correction or suchlike on an Ella Fitzgerald recording! People would riot.

* The regular, mainstream idol scene's take on pop is about as artificial and plastic as imaginable (awful stuff...), but the underground "alt-idol" scene, particularly in parts of Tokyo, has some brilliant songwriting and mind-blowing musicianship. Maybe the best prog-metal song of the last five years or more anywhere is a 14-minute epic by alt-idols Broken by the Scream, "Remembrance of Nazca." Who'da thunk?
