Well, off hand, these are some of the songs I listen to on my current rotation, that always cheer me up when I hear them. Either just simply feel good songs, or so emotionally charged that I come out the other side revitalized.
This one has been a staple of me for decades.
This one makes me cry with awesome tears pretty much every time I hear it. Mostly because of my internal video I have for the song, but still ,the song itself is pretty damn awesome. I find I don't particularly care for any of their other music that I've heard, but this song has fucking teeth.
And then this one, just always perks me up. I love these guys in pretty much everything they've done.
I'm sure there are others, but they're all I can think of atm.
