The phenomena which occurs after desperately trying to either pass or 5 star a song in Guitar Hero / Rock Band / or any other music game.

After trying for what seems like ages, then giving up for an extended period of time (usually when a new Halo/CoD comes out or something). You return to the song and easily complete your objective.
