old blues are my favorite followed by all kinds of jazz.
and also bright eyes, pedro the lion/dave bazan, dylan, cat stevens, nick drake, spoon, pinback, elliott smith, denali, jim croce, belle & sebastian, built to spill, otis redding, neutral milk hotel, jets to brazil, cursive, broken social scene ... i could go on and on and on.
and do you really have to rip on a band (marilyn manson) just because you don't understand and/or like it?
