When a cd is labeled either Parental Advisory Explicit Lyrics or Explicit content, what is the difference between content and lyrics. It is evident why most of Eminem's is content, but what about the others?

I thought content was like nudie pics on the inside...

Lyrics are the actual words, content could be people moaning; inhaling (i.e. doing drugs), etc.

I think the entire thing is shit, damn recording companies caved after Tippy and her little fundies got beat bad. Good thing that not ALL recording companies complied, I have a cd or two that through it's content and lyrics should have the pretty sticker, but don't. Frankly, if it has the sticker, it's mainstream and on a thieving music made with charts recording company.
