Why that song?

How do you find new music to listen to? One way is through video. Either from a show’s theme song or the soundtrack of a movie. Finding new singers and composers for that one song that you hear is so rewarding. The more we like the show the stronger the connection to the song. So that makes me wonder, would I have liked the song if I heard it on its own first or is it liked because it’s from the show and brings happy memories?
