Auditory changes?

Has anyone ever been so high that the music they are listening to speeds up, then slows down. and you can tune into the guitar, vocals, w/e, and you hear ever track their is? (a track for those who arent musicians is....when you go to record a cd you record everything at different times. there are all kinds of noises and little things in the back ground that the artist threw in to help the song sound more full bodied.) when smoking good bud, and listening to trippy music, you can hear everything you never noticed was there before. is this just me?

good ones to try it with-
Wastin' Time-Kid Rock
Swan Song-Down
Planet Caravan-Black Sabbath and Pantera(pantera covered it, and did it almost perfectly)

much more that I havent expiermented with...Tom petty, Allmen Brothers, etc, etc.

Nope, not just you. One of the many benefits of thc is how music sounds when you're high. I've never had the music speed up or anything, but to each his own.
