I think a problem might also be that there's a barrier to the gameplay itself. I usually play harder difficulties but Guitar Hero is like a completely different skillset. I remember playing on the lower difficulties and having to build up to Expert. That extra orange button at the end that makes it more buttons than fingers can be tricky at first.
Then there's certain song like pic-related where I feel like my fingers can't physically move fast enough even if my mind can.
