Track of the summer? Maybe not.
The track's base has elements typical of the Maceo Plex/Maetrik sound—droning bass, malfunctioning robotics and a whipping synthetic drum pattern that's been utilised twice already (to marvellous effect) in "Solar Detroit" and "Solitary Daze." Juxtaposing these elements with the vocal and tinkling bell motif makes it more unusual than your typical house track, but it lacks a build and release that might have made it more anthemic and less static.
There are some subtle tweaks on the "Late Night Mix," but none majorly distinguish it from the original. Plex is a talented, ambitious producer who could comfortably claim to have produced more than one "track of the summer." "When The Lights Are Out" isn't worthy of the same honour, though thousands might disagree.
