I listen to a lot of videogame and movie OSTs - right now, I've been listening to the Child of Light-OST on repeat, but I've got a playlist with a bunch of Okami, Zelda, Amelie from Montmartre and House of Flying Daggers - and also a bunch of instrumental music that isn't part of any soundtrack; it's just wordless.
But that's mainly for the thumbnailing/planning stages of the comic - I do 95% of my drawing (sketching, inking, colouring, etc; ie most of the bits that don't involve handling text or plotting) while listening to various podcasts. A lot of them are narrative history podcasts - The British History Podcast, History of Byzantium, History of Rome, Revolutions, You Must Remember This, etc. - but I also listen to a bunch of others. Lore, for example, and Welcome to Night Vale (though I'm a 1-2 episodes behind on that), Alice Isn't Dead, as well as actual play podcasts of tabletop rpgs, like The Adventure Zone and Friends at the Table and I also recently started listening/watching Critical Role.
Listening to podcast episodes help me focus on working for longer chunks of time (the podcasts I listen to have episode-lengths from 25 minutes a piece all the way up to 3+ hours), and also help me from getting bored and rushing through the bits of drawing I enjoy least - like bamboo forests, or rooftiles and paving stones.
