I've been searching for this song on the net today too, but then found out that Snoop Dogg sings "sweat" (not "swang" as I thought before)
So yeah, this song is remix by David Guetta of Snoop Dogg - Sweat (here's the link to youtube: youtube.com/watch?v=P_9rrCKXblg ). Hope this will help you sleep at night ;D
