The youngers Drift readers are saying, "do what"?
The more elder of us (Aging Hipster, I'm looking your way) are saying, "wow, that was a long time ago"!
The PMRC was an early 80s advocacy group that included several wives of prominent U.S. Senators, including Tipper Gore. They were upset at some of the lyrics of the day and demanded that the record companies take some action to protect the children. The result were the now very familiar Parental Warning labels. Being a teenager at the time, I was very passionate and vocal about such goings on. I actually used it as one of the reasons to not vote for Al Gore in 2000. I still cannot forgive Tipper.
Now the point of all this.
Shakespeare's Sister has a very interesting take on this bit of history. You can see my disagreement in the comments. You are welcome to comment here or there but comment you should. Definitely if you are one of us geezers that actually remember watching the hearings. Frank Zappa, god bless your departed soul.
