i dont know if it is necessarily the music that changes my mood.
or if its my mood that makes me want to listen to certain types of music.
if im in a bad mood im not going to want to listen to happy fun loud music.
ill listen to something more mellow.
or if im in a happy hyper mood there is no way im going to want to listen to death cab.
but there are times where if im listening to something mellow and quiet it might make me feel more tired or calm.
or if im upset if i listen to a fun dancy song it may lift my spirits a bit.
