New toss

Metallica and the Andean Pan Pipe Players: not even a big Metallica fan but this sounds high potential. Metal is already huge in S America, make this happen

Sinatra & Prince: RIP, but would be great

Chipmunks New Age: a gimmick but could be good for a laugh

Public Enemy covers Cole Porter: I can't envision it but pulling this off would be great. Furthermore I just learned that both Cole Porter and Public Enemy had a song "Public Enemy No. 1" Well played, Larsen!

Grandpa Jones and 500 Strings: nothing new here, how many times have I heard a guitarist with orchestral accompaniment, I've probably already heard it with a banjo a few times too

NKOTB: Boy/girl groups make me sick
