Anyone having problems with custom iTunes Radio stations?

I made one when the new iTunes first came out with about 10 different artists in them. At first, it played two songs. One by the main artists (First one I inputed) and then another song. After that, nothing.. I hit play again and again and no songs. Featured stations always work but my custom one no luck.

I tried again today, same thing. Two songs played and then nothing after that. When they show up on the iPhone, same problem, doesn't play. Wondering what's going on here...
