From head bang to mood swings

Dont know how to react to the sudden changes in my playlist over the few days. its been around 4 years now that i've been listening to rock. but it wasn't till about an year back that i transformed into a total black/death metal fanatic. used to just listen to the likes of godsmack, slayer, pantera, korn, megadeth etc. for the past few days though, i've completely gone into classic rock and psychadelic(except for the times, of course, when i m in ankur's room). i've seen my playlist giving way to floyd(my long time favorite), the doors, clapton, radiohead, the who, simon n garfunkel etc. cant get enough of them. no complains.
now playing : human touch, Bruce Springsteen
