what happened to Todays Blues on iTunes Radio?

I had this problem, too.
Go to: https://itunes.apple.com/us/station/todays-blues/idra.566510663

Click the Today's Blues link and it will open and play in iTunes. I can only think that the URL may have changed, I didn't check before deleting the old one from my list.

But that lasted only 10 minutes...

The url has changed, but the new ones craps out within a few minutes. This is the best station in iTunes Radio. Fix it Apple!

I agree. Today's Blues is (was?) my favorite station on iTunes Radio. I wish they would fix this. It stopped working on my iPhone, iPad, and Apple TV. I wish Apple would fix this. It's probably something very simple. Or at least give us an explanation or remove it entirely.

Thanks!

Apple has never seemed serious about Apple Radio. You want to see how to do this right, try Amazon Prime Music. It's terrific!
