I'm looking for joyful, happy, poppy music.
For examples of what I'm talking about...
Beatles - Here Comes the Sun
Third Eye Blind - Semi Charmed Life
Dispatch - Flying Horses, The General
Incubus - Dig
Jack Johnson - Upside Down
Or music that is just really beautiful. One of my favorite bands, The Decemberists, are a great example of this. I can't really describe it.
This youtube video is one of my favorite song of theirs, if you don't know them I'd recommend you take a listen.

So yeah. Any happy music you want to recommend, I'll listen to.
