Why is this cd 18 and over? Its just some Latin Funk type stuff. Doesn't make sense.

yes, but it's the latin-funk your mother warned you about.:D

Since when to Parental warning's make music 18 & over? it has yet to stop me.
The reason it has a Parental Advisory sticker is because the rappers they bring in use the "f-word", I think they might also swear in spanish (I don't know though, seeing as I don't speak it.) The people who do the stickers don't really listen to the music, they just review the lyrics and look for little "red flags" which they mark down, usually completely out of context. Personally I think parental advisory stickers are complete BS for the reasons like this. But, if it'll shut up the politicians about all the "bad music" that's corruptting kids these days, I guess I can live with it.

That sticker used to give a certain boost in sales...but I don't know it it's still the case.

Naw JMX, now it's banning that boosts sales. Banning and recalling albums.
