Well, I have a YouTube playlist of songs from the 80s, 90s, and 00s I listen to while I'm coloring my pages, which can sometimes give me ideas for future comics given my comic does a lot of stuff to do with nostalgia.
Otherwise, when I pencil and ink the pages... (Yes, I still use paper, pencils, and ink for my pages)...it's usually some Let's Play video of people I enjoy watching on YouTube.
