Push the Tag button, and later you can preview, purchase, and enjoy music with iTunes and your iPod.
Just when you thought there wasn’t anything else they could add to the iPod experience. Now HD Radio wants in on the success, so they are teaming up with Apple for a new free service called iTunes Tagging.
Basically when you’re rocking out to HD Radio and your favorite Foghat song comes on, you can just push the Tag button, and your system will mark that song for purchase on iTunes.
The service is a joint effort between Apple and iBiquity Digital, as well as the several broadcasters that need to implement the system on their radio stations.
And (thankfully), it doesn’t just work with Foghat. It’s perfect for all of those songs that you loved but had no clue who performed them. However, you will need a compatible system. Right now, the Polk I-Sonic Entertainment System 2 (shown) and the JBL iHD are the only two units that will have the Tag option.
Both the Polk and JBL products will be available in time for the holidays. Expect other products for the home and car to hit in 2008.

Color me unimpressed.
Now if this were HD radio reception on the iPod, that would be kinda cool. Better still would be an HD radio receiver that would record songs you like off the radio so you could play them back at your leisure on your iPod. I could get into that.
None of this makes me want to race out and buy a table top alarm clock with HD radio for $200+.
I think Apple has very little involvement. I mean, if someone else wants to direct them to iTunes, why would Apple care? Mo’ money for them… I think it’s HD Radio trying to get a bit of the iPod hook.
ea, it is not the big-deal it is made out to be - consumers have shunned table-top HD radio, so why should they spend $500 for a device that still requires AM-loop and externally-mounted FM-dipole antennas to even have a chance to pick up the fragile digital HD signals. This is far from having Apple actually including it as a part of the new iPod. This is all to late for HD Radio:
