While gaming, we have
this old thread.
I will say, however, on my note of "theme music" for characters, my earlier selections have changed slightly - "Amaranth (Instrumental) " has tended towards becoming Silva's theme rather than Skoll's - it fits her personal blend of heroism and rapidly changing mood better than his personality.While painting or modelling - I'll listen to pretty much anything in my collection. Might be Enya, Led Zeppelin, Vivaldi, Ultravox, Pink Floyd (lots of Pink Floyd), Tom Petty, Beatles, Rammstein, Queen, etc, etc.
There are certain pieces I turn towards depending on mood or creative block, but I've never quite understood the idea of having specific "painting soundtracks".
Often though, I'll put on TV or a film in the background instead. I've watched a lot of films I've been meaning to this way - not sure how I can keep focus on both at once, but it works.
General advice though, avoid comedy unless you want to get paint everywhere when you start laughing.
