Oddly, this reminds me of a dream I always had when I was little. It was always full of strange music, and your line 'I hit the same broken piano key again and again' really hit the mark for me.
Great imagery. I like the twisted-ness of this. Is this supposed to represent a love/hate relationship?
My only suggestion is with the line 'how you long to crash me between your fingers'. I think it would sound better with 'crush' instead of 'crash.'
