With an iTunes Tagging enabled HD Radio™ receiver you can. When you hear a song you like on your local FM HD Radio station, you simply hit the "tag" button. The song's info will be saved from your HD Radio receiver to your iPod®. The songs will show up in a playlist called "Tagged" in iTunes the next time you sync your iPod to your computer. So you can click, download and buy the songs you want directly from the Apple® iTunes Music Store.
With a brand new HD Radio receiver, you will be able to tag songs while you listen to your favorite music in pure crystal-clear digital sound. And if that isn't enough, many HD Radio stations now are broadcasting additional digital channels called HD2 and HD3, all subscription-free.

iTunes Tagging requires iTunes 7.4 or later. Compatible with iPod with video, iPod classic, iPod nano (3rd and 4th generation), iPod touch (1st and 2nd generation), iPhone, and iPhone 3G.
