Just a remark about TV themes. When I started listening to movie music at the beginning of the 80s listening to the score was a way to revisit the movie. Becausethere was no other way, While listening to it the movie played in my head. That is why I didn’t like the way John Williams sometimes plugged tracks together from very different parts of the movie. I wanted it the way it appeared in the movie.
Anyway, it never crossed my mind to listen to TV themes because you could hear it every week when your favourite shows aired.
