Little bit of confusion at Leaky Caudron:
Warner released a picture of Harry playing the piano with Slughorn in the background. Now there isn't any indication in the canon Harry played any instrument at all, not of the other characters being musical entertaining.
So this must be a Warner liberty and to be honest as welcome as the choir in PoA directed by Flitwick.

I remember from my teens that music; popular music had a great impack on my life and of my schoolmates: to be honest it was far more important then good grades at school. 
Nowadays I would say: we did not listen to it with our ears, but with our hormones. 
I may assume sort of like happens to Harry cum suo too;
only what kind of music or hits did Harry and his mates crave for?
And I don't mean just Weird Sisters, but the Muggle music of his teen days.
