What I listen to depends on the type of mood i'm in at a given time. If I need to really concentrate on my comic and if i'm pressed for time, I listen to music only. I don't really have a favorite music genre so I have a pretty big music selection ranging from reggae, jpop/jrock, kpop, video game music, metal, classical, 90s R&B, 80s etc. Too many to list xD!
If i'm in a laid back mood and not pressed for time, I'll listen to a combination of music and youtube scary stories and podcasts. I like the scary podcasts the most! I've recently become very addicted to the NoSleep Podcast and Black Tapes Podcast.
