This has probably been discussed a lot, but what older anime songs would you like to see covered?

Off of the top of my head, I'd love a PasuPare cover of Chocolat ni Muchuu, a HHW cover of Ojamajo Carnival, an Afterglow cover of Rinbu Revolution, and a PoPiPa cover of I am and a Roselia cover of Dearest from Inuyasha. Also!! A PoPiPa cover of Houki Boshi and an Afterglow cover of The Biggest Dreamer.

I'm out-of-the-loop with a lot of newer shows, so it makes me happy to see covers of songs from older series!
