I listen based on my mood. Sometimes I choose stuff that is relaxing to just that, relax. Other times I need to be upbeat and moving so I put on some disco or rock, it all depends.
Its calming and brings back sweet memories that almost has me reliving the moment. I guess you can call me sentimental.
I listen to Rock and Metal the whole time. Sometimes I listen to Dance, Pop or even Classical music. Rock and Metal are my favourite genres because when I am agressive the music helps me calm down. When I am in a high mood, I listen to Dance music. Classical music is only for relaxing.
Most of the music I listen to is either musical theatre or classical. I listen to the musical theatre because I appreciate the storytelling that happens. Listening to an entire album, it feels like you've experienced the entire show firsthand. I listen to classical music because I myself am an instrumentalist. I'm a classical oboist and listening to pieces before performing them offers more insight into how I'm supposed to shape lines.
