I know radio is a dying form of media but I live in Modesto, and every Saturday with the exception of a few I hear a show called Metropolis airing on 91.9 KCSS. It's a station out of Turlock and guess what THEY PLAY anime music and all kinds of Japanese, and Korean music very cool stuff.
Best part is you can listen to them from anywhere kcss.net and click stream and click the play button. They are on every Saturday (unless its a holiday or otherwise) 10am-12pm
I guess they have a facebook too Search Metropolis on 91.9 KCSS
It's a really good show the hosts are funny at times.
