I need help identifying this style of music?

Okay so this has been in the back of my mind for weeks, and I just
can't put my finger on it. It almost sounds like Burlesque style, but
not quite. It might be though, so don't rule it out. The style i'm
thinking of has a prominent Piano in it. Like, for the whole song or
most of it, the piano is hitting a single note or key in rhythm. It's
like bum bum bum bum bum bum bum bum bum bum, but "bum" being a Piano
note. This may have been the worst description you've ever heard, but
any help would be greatly appreciated. Thank You guys. And post
whatever you can think of, If you think it's wrong, It could be right.

Cheers
