@sollat I went absolutely nuts trying to track one of those songs once! I knew it was on Bones, but I didn't know the name of the episode (because this was before the days of talking TVs), and I didn't remember when it had aired or really much about it. Thank goodness a Sesame Street documentary I really wanted to see came on right after that, and I remembered when that was, so I found the episode from there. The song turned out to be You by Fisher.
