Was playing around with Fergie's London Bridge (The Song, obviously not whatever anatomical part she is describing) and realized Kroon from Kassin's Michiko To Hatchin soundtrack would fit pretty well, almost makes Fergie sound like M.I.A.
@piqued_interest: I like that instrumental. The vocals seem ever so slighly out of time, being most noticeable on the verses. Her delivery on the chorus and bridge actually fits really well with the instrumental. The shouting and the british accent fit well with the punk rockness of the beat. If you had a Lady Sovereign acapella it'd probably be cool on the verses.
I don't like the verses over it though, mostly because the timing seems off. Cool mix. I've played it starting from 1:27 like 10 times.
The whole Michiko To Hatchin soundtrack probably has the best music featured in any anime (Brazillian musician Kassin via Shinichiro Watanabe handling Music Production for the series) , A series that was outshone by the music 99 percent of the time -
It was a real quick session in Traktor DJ, definitely not perfectly beat-matched or harmonically mixed, but glad you enjoyed [parts] nonetheless.
(Looked at available Lady Sovereign acapellas and couldn't find any within a usable BPM range)
