Ah, you are speaking my language...80's hair bands/heavy metal music! The only site I know of, thought I have never been a fan of it, is the one started by Tipper Gore in the 80's that is responsible for those warning stickers you see on CD's. It's called the PMRC-Parents Music Resource Center. As for the bands you mentioned above I can tell you that Extreme (the sappy song More Than Words) is about as clean as it can get as is Slaughter. In fact, I was the head of the local fan club chapter for Slaughter "back in the day." LOL.... L.A. Guns is not too bad honestly for a 12 yr old. Their lyrics are pretty tame. As for Paramore and Breaking Benjamin, those are current bands, NOT from the 80's. Those band members were babies and little kids in the 80's for the most part. He is probably listening to Motley Crue (my personal all time fave), Cinderella, Aerosmith (which I'm sure you know), Warrant, Sid Row, etc... Honestly, they are all fine! Back in the 80's and early 90's the music for the most part, with exception of rap, was pretty tame. Nothing like today's music at all!! If you want to email me with a list of bands I will be happy to help you. Just send me a private message and I'll return the message with my email addy. Good luck!
