Sorry that's just you. As an amateur musician myself, music helps me concentrate. Actually, if I have been writing code for a while without music, I would notice that "something is missing" and turn on my music. I know a number of colleagues who use their headphones all the time as well.
"that's just you" is dismissive and inaccurate. I can only listen to music when I'm slacking and if I begin to do real work the music I normally enjoy becomes an annoyance and I have to turn it off.
I’m not not a developer, I work in the IT space and require deep focus for a myriad of other tasks (like anyone else, I presume). I’m no longer a musician but consider myself to have a rich musical background. Music does wonders for my focus, but it also generates fatigue. So I’m often alternating between music and silence. Have you noticed the same thing or is this less common?
