The song is about how using an all-powerful boombox might lead to both some rather fantastic and some just plain disgusting situations and, as such, it should be treated with caution. Coupled with a video it might be lyrically "lol"-worthy, but as it stands it's more smile/chuckle-inducing. As a song, however, it's surprisingly catchy and put me in quite a good mood. It also shows how easily Julian Casablancas could be an R'n'B/hip-hop star - if the beginning of 4th album recording (tomorrow) doesn't go well, at least he could release a solo album of R'n'B tunes, produced - of course - by Pharrell.
I would imagine an actual video might surface post-this Saturday, but until then this will have to suffice:
