Which songs are you thankful Glee didn’t cover?

Glee covered over 700 songs. I’ve seen posts where people wish they had covered certain songs, but I wonder which songs you are glad they didn’t touch. They avoided most alternative and modern rock bands and light rock. They focused a lot on pop, musicals, and classic rock and pop, thankfully with some r&b.

? For example, I think there was only two Elvis songs (although I forgot about A little Less Conversation because I skip that episode), and I’m happy they didn’t. I’m glad they didn’t try to tackle Linkin Park or Panic at the Disco (although I would’ve loved to hear Elliott tackle Brandon Urie’s vocals. Are there any songs you are glad they avoided?
