Tough one - I don't listen to a whole lot of music, but as I usually just play Billy Joel on my piano I would go with a lot of his songs.
New York State of Mind, Lullabye, Baby Grand, Piano Man, are just a few of my favourites.
My fav music player is of course - my piano!! Heheh! <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
