Younger fans might find this harder to believe, but back in the day that little "Parental Advisory" sticker was a real fence to climb. Sort of like how you can't get into a rated-R movie, you couldn't buy an album with too much explicit material (Read: Every rap album worth owning). But nowadays, thanks to the awesome powers of the Internet, you can just download everything you ever wanted without Pirate Bay asking you if you're 18 or not.
