When I write I need either background instrumental music (classical, movie soundtracks, low-fi beats; Spotify's got a lot of great playlists) or an album I've listened to a million times.
When I draw, I find I prefer podcasts so I can kinda zone out of the actual drawing process and just sorta, do it? Music gets kinda boring after a while. My mind will start to wander to shadowy places if I'm not sufficiently distracted. 9_9
In summation:
If I need to think: Music!
If I don't: Podcasts!
(Bonus! - If I'm STREAMING while drawing: background music and chatting with folks! In other words, both?!)
