Do you mean the SP: Chef Aid album? The reason I ask is that as far as I know, the only soundtrack available is for the SP movie and it is not censored at all.
Chef Aid has two versions. There is a clean version (even though there still is a Parental Advisory sticker on it). It comes in two covers: the original one with the kids standing in front of the stage and an orange colored one.
The explicit, extreme version has one cover (the original one) and it has a red "EXTREME" sticker on it with the Parental Advisory sticker.
The clean version does contain some language (like one or two F-words), but most of the songs have had the bad words censored out. The extreme version has tons more F-words and the last song has more explicit soundbytes from past SP TV shows, unlike in the cleaner version.
Take note: the clean version is NOT 100% clean. It's an R-rated version. The extreme version is a HARD-R-rated version.
