i usually skip me and the minibar, modern moonlight and truce. it's not that i don't like them, i just don't love them. then again, i used to skip gravity, until i read that story about it in the companion. it touched me so i started listening to the song again and it's been my favourite song ever since. that was about three years ago.
come to think of it, most of the songs i used to skip are now among my favourites. the ones i used to love (coin-op and girl anachronism) are now much lower on my list. i still love them, just not as much as i used to.
