Music game revisited

In the 'things on the internet' portion of last post, I forgot to mention Kate Beaton's comics. She's getting kind of famous now, at least if Shaenon Garrity and Ryan North linking to her is any indication, but maybe you haven't seen them yet, and you really should. (I think I found them through angrylemur.)

Speaking of angrylemur and stuff inspired in this entry by same, a while ago she posted that song lyric guessing game I like, and it made me notice that it's been almost two years since the last time I did it myself, which naturally awakened a resolve to do it again. I was going to wait until after I'd posted more of the things of actual substance I've been intending to write for this journal, but it's occurred to me that this actually takes way less time than those things, so it's not like it's delaying them significantly to do it now. I am going for it.

Here follows the list. It's 20 first lines again (even though Ms. Lemur did 16), and I'm not going to make it zero-sum, so I encourage people to guess before looking at anyone else's answers.
