I've got thirty other bones to pick with RB3 tiers before we reach Antibodies. Antibodies is basically the same problem pattern as Rio guitar, which is...three? four? dots. That's a small move compared to The Look on bass.

@V8VANTAGE If it is a red herring, another interpretation would be the original version of a song being the oldest song in the library but us getting a modern cover so like for example the Five Finger Death Punch cover of House of the Rising Sun.
May sees the oldest song officially released.
