Albums Lilz and Patrick might cover in future episodes
"Love Beach" by Emerson, Lake & Palmer: It's inevitable that they will eventually cover it, not any time soon, however, as it would mean having to retire their Running Gag.
"Lulu" by Metallica and Lou Reed - Said that they will eventually cover it. Not any time soon, however, considering they reviewed St. Anger for Season 2.
"Never Let Me Down" by David Bowie: Said in the episode covering "Tonight" that they will eventually cover this album, considering that both albums are equally reviled.
