I find that audiobooks are great for when I'm painting, but finding good scifi books can be hard sometimes. And if I can't concentrate on the book I usually switch over to my spotify playlist, basically a mish mash of different kinds of metal, anything from Iron Maiden, Sabaton (great 40k music as they have a WWII theme on most of their stuff), Danzig, Judas Priest, to heavier stuff such as Entombed, Graveworm and Raubtier gets my painting mood going.
Some of the bands mentioned above are probably to small and/or regional for most of BoLS members, so here are some links for those interested in metal music.
