I had Salt-n-Peppa mashed with The Stooges here but changed it because, while it's good, it's hard to listen to for a full 3 minutes. I'll touch on that later this week, but the replacement I find pretty interesting, though maybe not a true mashup. BRAT (who does most of the mashups I've posted) apparently works for Depeche Mode and can get unprecedented DM source material. In this one, he puts the actual DM vocals on a 3rd party ska instrumental cover. It works pretty well.
