Idea

okay, so i think they should definitely add a back up singer and a rythm guitarist.
this would be so cool

the singer would play the rythm guitar, and the bassist would be the back up singer
rythm guitar would be perfect for songs like more than a feeling and back up singer fits for sooo many different songs its not even funny.

also a synthesizer/piano would be kind of fun if they added songs like "here in your arms" by hellogoodbye and stuff like that

excellent, although it should be optional. I wouldn't make it a requirement for two reasons: I don't know where on the screen you would put two more charts and the overall difficulty of reading the lyrics and pitches along with the guitar charts

all instruments should be optional, if a song only has a bass and a drum part then it should be allowed in the game as much as a song with two singers, drummer, lead, rhythm and bass
