SEE AN AURAL SURGEON..
you need your ears cleaned out, coz you are hearing things that are not there. the mind is amazing at filling in gaps or making you think you hear what isnt there. which seems to be the case here.
try "QUEEN's GREATEST HITS" backwards, now there's some disturbing backtracking for you.
ALICE COOPER it is said, also done backtracking on some albums.
improve the sound quality.........
have a nice day.......
