iTunes Radio won't play music

Same here. I rarely listen to iTunes radio, but I tried a little while ago and got the same error as you:

An error occurred while contacting the radio tuning service. Check your Internet connection, or try again later.

I just posted the same thing on itunes radio. Same error message - Started yesterday. Everything else on itunes is working, including the store. I phoned my server and they think it is an apple issue. Can't get into itunes apple with the question except to pay $10.00.

Or go directly to your fav radio station online. Most radio stations have online streaming from their station on the internet.

Apple has quit supporting iTunes music stations on the older iTunes 10.6.3. The best thing to do is to go to addictedtoradio.com and stream your favorite music type directly from there. I used to use iTunes radio to get me there anyway, so now I just bypass the Apple end of it and use the station directly. There is no cost and you get to beat Apple by keeping your older PowerPC music source (laptop, tower, mini, iMac, etc.) instead of having to upgrade out of necessity. 🙂

Wow, how disappointing. Here at my office, I used and enjoyed iTunes 10.6.3 on my G5 almost every day. Yes, I get the fact that technology marches on, but why shut off this service to those who don't have (or can afford) a newer computer? As much as I like Apple, it's stuff like this that really turns me off.

A good alternative to iTunes Radio on a Mac PPC is VLC Media Player. I'm listening to it now, version 2.0.10, on my G5 running OS 10.5.8. There are hundreds of "stations" to pick from under their "Icecast Radio Directory." It is definitely not the prettiest app out there, but the selection of music and sound quality is every bit (so to speak) as good as iTunes.
