What songs make you happy?

Everyone's got that one song (or whole playlist) of music that can completely change their mood around.

Mine include:
Here it Goes Again - OK Go,
Bucky Done Gone - M.I.A.,
M79 - Vampire Weekend,
Canon - Pachelbel,
And many more..

What song cheers you up? It can be because of the words, the rhythm, or just the overall sound.

And, in completely unrelated news...Canada Day is on Wednesday, and I fully expect the Mibba logo to be decked out in red and white.

This sentence should be about thirteen words long or something like that. Damn.
