Sad song reccomendations? (Non-JPop)

[m-a-z-e]

I was wondering if anyone could reccomend any sad songs? I need a bit of inspiration for a series of screenplays I've started to write. Buffy the vampire slayer-esque. I just need a wide variety of sad songs for the more upsetting and depressing moments that you'd have in a show like this. So if anyone could help me it'd be greatly appreciated!
