require cd's to have "Parental Advisory" labels for sexual lyrics and pictures inside the liner notes

Back in the early 2000's, albums used to have parental advisory stickers for sexual content, risque pictures in the liner notes and even the word "damn." Its also been recently that less and less albums are having labels for saying the f word or the s word. When people buy an album with no label like this, they expect it to be a clean album that is safe to listen to with their children. It has sadly become less and less true. I would like the Obama Administration to address this and hopefully require artists to put these labels on their albums again so people can know what they are buying. Also people should have to present and ID to purchase an album with this label as you used to have to be 18+ to buy one. Thank you.
