Huh. I hope there weren't any translation errors in the list of names I gave for Evangelion I. Someone might have to check them over.
Anyway, the worst example I've found of overly-compressed music (which definitely affects anime more than VGM, in my experience) is the Hikaru Utada song for Rebuild of Evangelion.
That's just insane. It hurts my ears just looking at it, let alone listening...
(That is a compressed MP3, though, but on the macro level you wouldn't see much difference if it weren't.)
