Song suggestions for getting over a broken heart/bad time in general?

My best friend just got her heart broken (by a JERK of a guy!) so I was thinking of making her a playlist of songs about getting over a guy, or just really hopeful songs in general, about bad times getting better. She’s really torn up about this, not sure if she can move on, etc, and I just want to do something for her to help.

+Genres don’t really matter, but if you think it does, she really prefers bands like All Time Low, A Rocket to the Moon. But anything goes, from Matt Wertz to George Michael.
