Is listening to music a hobby?

Yeah I’m pretty sure listening to music is a hobby, granted there are different sub subgroups within music that can be considered a hobby. There’s folks who collect albums/CDs/Vinyls, some people are audiophiles, and some collect memorabilia related to the music they listen to. I’m pretty sure listening would be a hobby since your actively following it and putting dedication/hours into listening, just like you would do with other hobbies.

I think you can, you're learning and self-developing in the field of music.
