Sometimes when we hear a certain nice song on the radio but that we are unfamiliar with, how we would wish to be able to "remember" or tag it so we can buy it and listen to it again. I know I have often find myself in such a situation. Well, the good news is we can do so now with iTunes Tagging.
This technology uses a high definition radio that you can simply press the "tag" button to save the song. The information of the song will be saved from your HD Radio receiver to your iPod. The songs will appear on the playlist as "Tagged" in iTunes which you can then sync it with your computer. So you can click, download and buy the songs you want directly from the Apple® iTunes Music Store. It is fast and easy.
And if this is not reason enough to get a HD Radio, it has additional new radio stations that plays digital channels called HD2 and HD3, all subscription-free.
