The DJ's Take: Heard this on the radio the other day, and it reminded me a lot of Cruel Summer by Bananarama (which could be a nice little mix or mashup if you spin 80s music). Worth a download if you play Top 40 and you're not too worried whether people are dancing or not. If you want to stay key-compatible (and get a little unconventional), try mixing with tracks like Mo Money Mo Problems, Love More, and Turn Me On.
