Thank you! I dunno about OSTs good for painting, I prefer something more dynamic, like Hotline Miami soundtrack.

To The Moon OST

Gracias

Thank you for the chance!

Bastion - A fantastic game with a fantastic soundtrack.
Transistor - Darren Korb, the maker of the Bastion soundtrack, does it again. There are two version of this soundtrack. Normal and Hummed. The Hummed version of Sandbox still sends chills down my spine.
FTL - A soundtrack that fits my most favorite roguelike really well. The free soundtrack of the Advanced expansion is also awesome.
Fate/Stay Night Realta Nua - My all time favorite game also has a very nice and varied soundtrack.
SimCity 2013 -Too bad the game is so awful, some of the tracks in this are really memorable. My two favorites are "Population -1" - a very calm and inspirational track and "The Long Construction" - Starts out calm and quite and ends up very loud and energetic.
Dragon Ball Z - American Soundtrack by Bruce Faulconer - My childhood anime. I grew up watching DBZ and listening to many fantastic tunes by Bruce. Watching DBZ without his tunes in the background is impossible for me.
Naruto - From episode 1, I was sucked into the anime and its soundtrack that can really make your heart pound.
Death Note - A fantastic anime that has an absolutely stellar soundtrack.

And my final recommendation would be: http://www.streamingsoundtracks.com/ My most favorite internet radio station. They steam soundtracks 24/7 and I always use it when I study or do some creative work.

Phew, I wasn't planning to recommend as many, but soundtrack is my favorite genre of music, so I had to name a few of my favorites. Hope you find something useful. :)

'Cognition' is my current fav game ost. Bastion's good, too. For movies, I like almost anything by James Horner or Steve jablonski

Endless Space, is very relaxing

Thanks

An OST, eh?
If you're fine with anime OST's, then I can most certainly recommend the OST from Mekaku City Actors.
