Oh didn't know it was Warner, in that case more than likely they have put the finishing touches at their studio. But that ain't necessarily the case, most producers have their own small home studios where a track like this is very easy to make.
Nowadays professional studios like one at Warner are mostly needed for recording bands with instruments (drums, bass, guitars etc) and vocals. Even a small home studio works perfectly well for all kinds of electronic music.
There were some talk on mirc whudunnit so I figured it was made at home but yeah, could very well be finalized at Warner since they distribute it.
