Guitar Hero 5

This is, for most, an easy enough task. You can do this on any song, on any instrument, on any difficulty, in either Quickplay or Career Mode. The maximum number of stars available in Quickplay is 6 stars (for a full combo), and for Career Mode is 9 stars (depending on how you do at the challenge). If you want to get it really easily, you can put a microphone by a fan or the TV speaker and play on Beginner difficulty vocals, and you will score 5 (most likely 6) stars for whichever song you choose.
