Hahahahahah, yes. There's like seven gazillion variations on "baby, how could you cheat on me" and "fuck you, you fucking cheating fucktard, I am fucking done with you" songs. There aren't really that many for "look, I srsly love both of these people but I can't help lying because I don't want to lose HIM and I also can't help shagging HIM because I can't bear living with the knowledge of another missed chance but I'm REALLY REALLY conflicted about it all, honest." C'MON, SONGWRITERS, A LITTLE COMPLEXITY, HERE!
I'm not the hugest Tegan & Sara fan usually but I love Dark Come Now. The Ingrid Michaelson one is great because YAY BOUNCY BUY STABBY. And To Build A Home just about killed me, argh.
