song heard in forever 21 store yesterday

i heard a really good house or techno version/edit of beyonce's "crazy in love" yesterday in forever 21, but can't find it anywhere. thing is, i'm not sure if it would be considered a remix or not, because it just uses a sample of the "uh oh uh oh uh oh oh no no" that loops over the beat. There aren't any other lyrics from the song (maybe 1 or 2 lines I didn't catch).

eta: Just in case the playlist that the song is from isn't the March 2009 one, which hasn't been posted anywhere, other songs on this playlist were will.i.am "I got it from my mama", a remix of "Hearts on fire" by cut copy and some song that was either by Amy Winehouse or someone that sounded exactly like her.

eta again: the playlist also had kudu's "bar star" (porn star?) on it. sorry, i'm really obsessed with finding this song, especially because i have pretty much no lyrics to go on.
