Guitar Hero II Glitches

Easy 5 stars
Go to practice and choose any section of any song. Put it on any speed (preferably slowest) and play it. Then, right at the end, unplug the controller and plug it back in. The fretboard should keep moving endlessly. Then go to quickplay and play that song. It should only have the section you practiced with playing and the rest is nothing else. This glitch lets you get 5 stars on any song, but may take a few tries.
