Is it bad if I listen to music alot?

When I say alot I mean, I have my iPod on during school all the time
except when I'm doing a test or a special teacher comes in and teaches
us something different (dance instructor, health teacher, etc. I
listen to my iPod while riding home on the bus, outside at recess and
even at home. Most of the day I would have headphones on but f I'm
downstairs I plug it into my surround sound and play video games while
listening. I even listen to music to help me fall asleep( I set a
timer so it sleeps).

I listen to k-pop so most of my music is soft but some are upbeat. I
keep my iPod at a good volume so I can hear everything around me too.
I also noticed I'm more focused when studying and doing work when I'm
listening to music.

So am I doing anything bad? Should I cut back?

P.S. I'm in my last uer of elementary school and I know that I won't
be allowed to listen to music during class on highschool. My teacher
doesn't mind if we listen to music during class, as long as we're
doing work and can still hear him. When he wants me to take my
headphones off I do
