iPod hero
When a song you want to play on guitar hero/rockband isn't on the game, so you get your iPod/MP3, mute your TV, and play a random song on the game pretending to play the song being played on your iPod. works best when the random song is of the same genera as the song you play on your iPod.
I was tired of all the songs on Guitar Hero 3, so I got my iPod and played iPod hero
