A mix of songs played by Harry during his DJ set at Dominic Jones's London Fashion Week after-party at The Box. This is according to various sources so I'm not sure how accurate it is.
FYI: I don't know how long his set went on & I could only find 7 songs mentioned in all.

Updated 4/22/13: I've added the tracks he chose for the Radio1 takeover with Nick Grimshaw back in October 2012 aka LadsFM

13 tracks
