This category was suggest by blue

Whaaa! My computer got a virus a month ago and I *just* got it back last night. I was working on a list of nominees for this category. Must find it and report back.

I just realized that the poll for this category did not show up. I know people came up with great ideas. Please suggest nominees for best use of a song in the show. I will repost this question with the nominees. Thanks to everyone who votes.
