Be honest: if you've watched Bob Ross' The Joy of Painting, it was probably more for his ultra-relaxing voice than his artistic advice. More than a few people have admitted to nodding off to his episodes. If so, you'll be glad to hear that his dulcet tones are available on-demand through your phone. Calm has released an officially approved Bob Ross Sleep Story recording for its mobile app (simply titled Painting With Bob Ross) that, as you might guess, uses snippets from the artist's PBS show to help your slumber. You no longer have to leave a YouTube video open or find a way to grab the raw audio.
