Um_nik yes

I do

Yes!

Listening to Broken Ties — The Whistlers remix increases your brain power.

No, i find it really distracting

It really depends. For me, chillin' music (instrumental) can help me to be focus on somthing better. However, not everyone can have the same feeling as me. I do not try to concentrate on the playing music; it just creates an environment that there's no noise or other sounds.

Yes, I listen to music during a contest. It helps me lock in on the contest. I find that random artists screaming random words in my ear really helps me formalize my thought process. This is not sarcasm. ;)

Most of the times some anime background music or intro... Somehow it just helps me in staying focussed.

Yes, but only relaxing / low tempo stuff. I like Luna Li, Liana Flores and Ichiko Aoba for example.

If I put on some rock music I'm not concentrating well enough :)

I use brown noise to block outside noises

Yes! I can't go long implementation without BGM (TBH, in ICPC onsite contests, no BGM 5-hour is every time painful for me...).

Hardcore/Speedcore enjoyer here. The harder the music, the better.

I break away from the outside world during the contest(joke)

I've tried but I can't concentrate and think if there's music in the bg

I usually listen to skyrim night ambient or random synthwave playlists. I listen to it because it gives me a sense of flow and removes external distractions, but I usually turn it off when I need to focus really hard.

 RADIOHEAD!!!

only when I'm writing data structure problems

Yes when doing very easy problems like A and B. I've heard that a study (or research, I can't remember it) shows that listening to music makes your brain more active and speed faster when doing some simple tasks, like copying or doing the problems that you can come up with the solution at a glance. But it will distract yourself when you are intensively thinking.

I used to listen, but I realized now that I do better when I don't listen to music. Sometimes when I don't think and just code I like to put on some fast-paced heavier music.

Yes.

I would like to listen to some jpop music :)

Yes!

Yes ,I am very fond of listening to Interstellar Background Music while solving problems

I like to listen music when doing a casual implementation in practicing. In contests I find it distracting and feel like I do worse when listening so I dont listen in contests and vc's.

yeah. i always listen to music while writing code!

problemset yes contest no

nah very annoying , i usually listen to my thinking and so any sounds annoy me

yes, goat nujabes and shing02

good idea

CP is hard so I don't listen to music when participating in contests.

Music is relaxing so I do participate in contests when listen music.

Not during a contest, but Yes while practising.

In contests, music just sounds too grating. Imo, ASMR is much more suitable for contests.

yes
