#7 -- Bjork, Hyperballad (I was just listening to this song!)
#9 -- Hallelujah, by Leonard Cohen or that other guy, or covered by Duncan Sheik
#12 -- Time after Time, Cyndi Lauper
#19 -- Jeremy, Pearl Jam

I really want to say #6 is Ice, Ice Baby by Vanilla Ice, but that lyric is short enough that it could be something else.
