When I paint I usually listen to podcasts. The latest one that I've been listening to is the H.P. Lovecraft Literary Podcast.
I initially got interested in it because they were discussing classic ghost/horror stories that are my favourite to read. But I caught up with those in no time so I went back and started listening from the first episode.
If you are a Lovecraft fan, I think you will enjoy this podcast. The hosts are very humorous and keep your attention. They have guest hosts who usually have something Lovecrafty about them, and the people who narrate certain parts of the stories are usually top notch!
