Good riddance.
The PMRC was only effective because large retailers (Target, Walmart, Tower) could be pressured by religious groups not to carry albums with the PMRC sticker. It was the retailers that permitted conservatives to de-facto censor culture.
If you're listening to music you can buy at Target you need to broaden your horizons. You have always needed to broaden your horizons. Last year, Bandcamp had approximately 18,000 titles for sale... if you only count releases that were also available on mutherfuckin' cassette.
The manufacturing cost of a CD, if you're a naif in your dorm room willing to pay retail, is less than $3 ea. If you're one of those 100 titles it's more like 70 cents... in 1995. Books have been sold this way for a century or more and the reproduction costs on a book are an order of magnitude higher than for a CD.
Let them rot.
