The "R0kk_0n" glitch
This glitch allows you to take any song part and play it over any song that you want. Here's what you need to do:

1. Choose your song.
2. Enter practice mode.
3. Pick the section you want to play.
4. Start that section on any speed (slowest is easiest to perform the glitch).
5. Unplug controller right when the options screen comes back up at the end of the section.
6. Reinsert controller and press [Continue]. If note chart keeps scrolling, you performed the glitch.
7. Reset your PS2/Xbox 360 (heeheehee) to undo the glitch.
