This may not be easy, but...
It's a dancey song with male vocals. I was sure it was Gnarls Barkley when I heard it but I have checked out both albums and it isn't on either.
There's classic ravey piano throughout it except when it drops in the middle and ends up sounding a bit like Kadoc's Nighttrain

(the bit that comes in at 40sec, though the song I heard was a little slower)

Any ideas?
