Last year, TRONICBOX shared a remix of Justin Bieber's "What Do You Mean?" that was as much a convincing '80s throwback as it was a carefully crafted pop ballad. A new version of TRONICBOX's tune comes courtesy of PC Music's A.G Cook, as Tiny Mix Tapes points out. Now titled "Whaaat 85," Cook's version treats the remix like a time capsule retrieved in the future: it retains some retro elements while adding a hyperactive future-footwork sound no Reagan-era artist could have imagined.
