I just did a really damned cursory overview of my CDs (and Mrs Anarky's).
First, how the
fuck did they skip Amorica?
Next up, an oldie but a goodie. Joan may kick her ass, but it doesn't make this one any less hot, silly hairdo or not.
A mediocre new album from a self-proclaimed bitch who used to break all the rules. Her new music sucks, but her new album covers are much better.
Two that are more for the hot expressions than any actual imagery:

"Oh, I am so cute and naive and innocent. What are you going to do with that penis?"

"I'll tell you what you're going to do! You're going to stick it in me, and then we're going to sacrifice some puppies to the lord of darkness, but I'm still fucking hot!"
Possibly the most suggestive, though not obvious album cover:
I always rather liked this one, though Anthony Kiedis kinda spoils it:
Something about this one is simultaneously sexy as hell, and creepy as fuck:
Can't decide which of these is best. Nothing obvious, but Jewel could be wearing a fucking gorilla costume and covered in dog shit, and she'd still be hot. By her appearing on a cover, it becomes sexy by default.
I didn't forget Ms Jett, but she's too concerned with fucking to make sexy album covers.
