Music is pretty much my number 1 inspiration! I think besides dreams. I've had characters, story lines and entire series be inspired by music.
I have a series which I created a teaser to be printed and just wrote the first issue of called "Gorillas" based off a song by Army of the Pharaohs. Then there's another series I'm also writing right now called "March On" which is based off of Hip Hop as a whole with some House thrown in. Kinda funny to me two series I'm working on are so Hop Hop inspired because I'm more of a dance music guy. Well, pretty much everything else I've come up with is inspired by some form of as they call it now "EDM" because there's so many genres and I'm not about to sit here naming all of the ones that inspired me.
Since I listen to SO MUCH it's hard to just pick I'll go with what I'm listening to now which is video game music. I'm listening to my favorite video game soundtrack ever which are the Streets of Rage trilogy soundtracks. Here's the soundtrack for part 1. Go here, click play all and have it play in the background of whatever you're doing. See how it works for you https://www.youtube.com/playlist?list=PLEAD8D2B6A61E9544
