Friendship Songs?

[fandom-geek.livejournal.com]

I don't have the most extensive knowledge of bands and songs, and that's a real problem for me as a vidder. Could you guys help me out and list some good friendship-type songs? Love songs are good too, especially if they could be read as friendship only if necessary.

Maybe some that aren't necessarily older well-known songs? Something like "Lean On Me" would make a cutesy sort of video, but I was thinking maybe something more along the lines of "Everything" by Lifehouse, only I can't use that one because it's either spiritual or romantic, and you can't really use it for a non-romantic friendship.
