For myself I rarely listen to music in the daytime , the only time I listen to cd's are at night when I am falling asleep . Some music even effects my dreams . Ha I remember once (in my dream) I was at an opeth concert , the day before the dream in real life I was talking to somebody and they said that opeth weren't that good live , anyway back to the dream , I was at the show and In Flames finnished and then nevermore played and then Opeth came (these were the order that the cd's played in my cd player while I was sleeping) when opeth came on they sounded exactly like on the cd , I was freaked out , going nuts headbanging and everything , then they played creedence and i calmed down and talked to my friend who was there , ironically I said they sounded exactly like the cd . Ha ha , weird dream
