Harmonix is chumming the waters to see what sort of fan reaction they get by suggesting standalone Rock Band titles for artists like Led Zeppelin, Pink Floyd, U2, and more. Would you buy any of those?
Pink Floyd's Dark Side of the Moon is an all-time rock classic, but that's provided you're listening to it on a record. And maybe smashed off your face. Things are a little different when it sounds like a NES game.
