thanks for explaining. Personal musical interest is a huge part and would certainly explain why we search for new music through artists we already know. I had imagined plenty of people on a music thread on reddit, would have an general interest in music. I think I was focusing more on the why we listen. So in that instance, once you've found something, why would you continue to listen to it/what would motivate that. That's sort of where I got my ideas of 1.matching how we currently feel 2. matching how we want to feel and the third suggestion from this thread of how we used to feel.
