Apparently, this "contacting tuning services" and "An error occurred while contacting the radio tuning service...Check your Internet connection, or try again later" are not new to iTunes. There several instances posted on Apple forum going back to 2012.
Never cared for iTunes except to listen to the Internet radio...why can't Apple either fix this or get rid the worthlessness!

TrenttonY...yes, I didn't get the error message until I closed iTunes (had been playing music from an iPod and didn't noticed it was continuously trying to connect). I will also add resetting cache doesn't work.
