Is there a song that you like to listen to get you in a better mood?

[I Stomp on Kittens]

Self-Esteem by The Offspring. The part in the song about the girl being drunk and knocking on his door is so great in many ways and the song just makes me feel good!
Also, Dry Bone Valley by Mastodon!

 

[Bob_Dobb]

... We're no strangers to love... Seriously though, Through the Fire and the Flames or Where Dragons Rule by Dragonforce.

Spoiler

 

[Lashus]

Can't Stop by Red Hot Chili Peppers

also Hump de Bump

 

[Pappeska]

I got quite a few. Depending on if I'm depressed, anxious, agitated or wherever my mood is. But the song I can listen to in any given state is Luke Kelly - Farewell to Carlingford.
