Yup. I love this song too. Probably my favorite 80's song. It's not nostalgic to me since I never heard it when I was a kid, but got into it recently from hearing it at work. I always sing along to it. :P

Hmmm...never knew there was a Mission Impossible tv series.

Which Star Trek?

Adding Star Trek: TNG to my list.

Games too many to list. A lot of the VGM I listened to as a kid/teen bring memories and feelings to me when I listen to them now.
But a few really strong nostalgic ones are Super Metroid, Rygar (NES) and Batman (NES).

For TV: The Real Ghost Busters theme song. Love that song to this day.
