Unless it is something like shamanic drumming or primitive instruments, repetition in general for me is rather rage inducing, and not in a good way. I find almost all video game music extremely repetitive and immersion breaking, so much so that one of the first things I do is turn it off, can listen to just the music at another time. About the only time I can stand to listen to music while playing a game is if it is some sort of pvp melee dogpile and I have folk/death metal in the background. Otherwise, I just want environmental sounds or silence.
I don't mind piano but it seems to be lacking in personality on its own. It can be the dominant instrument but needs something with it. I could see something similar to this as intro music for something or maybe for some sort of action scene.
