Ah yeah, Macklemore & Ryan Lewis – Can’t Hold Us (feat. Ray Dalton). The song is pretty popular atm… I’ve seen them perform on SNL, Late Show with David Letterman, and Conan, and the song is being used in Microsoft’s Outlook.com ads (that’s actually where I first heard it). In fact, it was pretty funny when the Outlook.com ad was shown and shortly after they performed it on SNL when SNL returned. Seems to be an independent artist.
