Hmm a bad day.......
if I wana wallow a bit on a bad day a bit of Leonard Cohen or Neil Young will do.....

BUT

I prefer something to lift my spirits so I'm more likely to go for something heavy like Led Zepps Dazed and Confused, or something from Muse, or U2

Depends if im angry or upset/relfective;

Upset or reflective then easy answer: Ara Batur by Sigur Ros

The other one: ... i dunno probably just RATM or something lol

Complete control - The Clash

Daniel powter - Bad day

The video is lovely as well, love this song

On a bad day I vent my anger and frustrations by dancing and singing along with the entire album "Appetite for destruction" by Guns n' Roses.

Excellent anger management!

Plenty of anger and angst in half the music I listen to! If I had to mention one band, perhaps it would be Hatebreed - very angry young men!!

Pick of their tunes would be DESTROY EVERYTHING!!!!

if im having a bad day, jason mraz.... especially details in the fabric..awesome song for cheering urself up
