Someday I'm going to work for whatever organization decides that albums should have "explicit content" stickers (or are they self-selected? I dunno), and I'm going to impose a rule of my own: any album where the first single sounds totally different from the rest of the disc gets its own warning sticker.
Luckily, I now have free.napster.com to protect me from CDs that aren't nearly as good as their singles.
For example: Jape—Floating is good, and the CD it is from is not.
Update: Since this blog educates as it entertains, I feel compelled to inform you that the parental advisory sticker is indeed self-selected; there is no group who decides what it goes on as there is for movie ratings.
