Played this with 2 of my friends when I was a kid and we didn't care about the soundtrack, because we were able to play Mr Roboto by Styx in a video game with a fucking GUITAR, DRUMSET, AND MICROPHONE!! There was also a 4-player gamemode where you could connect 2 DS's to the wii and have the 2 wii players compete for score in a song, while the DS players would be each player's roadie and sabotage/help the wii players by setting their fretboard on fire, or making the notes turn invisible, or reversing their left and rights, and stuff like that.
