Go to Quick Play or Tour mode and have the microphone available. Choose "So Watcha Want" by the Beastie Boys under the Expert difficulty setting. When the song begins, put the microphone up to your speaker(s) and hold it there for the duration of the song. The only thing you will have to do is yell to activate Overdrive when it appears and tap the microphone for the solo parts. When the song ends you will have a 100% rank and gold stars. Note: Make sure your volume is loud enough. Note: For just a gold star, select "Give It Away" by the Red Hot Chili Peppers and do the same thing. You will get a 99% rank without singing. If you want a 100% rank on that song you must be able to hit the last phrase in the song.
