>>2261272The way I see it, listening to music is distracting enough to make a marginal detriment to the quality of your work. I'm pretty sure there's plenty of science about people on average being shit at multitasking - and listening to music while drawing is multitasking whether you're paying attention or not, especially stuff with lyrics - specifically lyrics in a language you can understand - and music you really enjoy.
However for many people, not having music can just make them anxious, impatient, and be a greater detriment to their work.
If listening to music keeps you focused longer, even if it is slightly more distracting than without, it's still better off and more productive.
The best option for a middle-ground between having music and being as efficient as you can with that in mind is probably music without lyrics that's mostly ambient, stuff you won't get really into.
