Apple introduced their next generation iPod Nano yesterday which comes with a new marketing feature called "iTunes Tagging." This nifty little feature is going to be hot and one of the most appreciated features over the years. We've all been there. We hear a tune on the radio and missed the DJ's description of the tune – or they ripped it off too quickly to catch. Yikes – it's a tune you want, a tune you can't get out of your head and you just can't find the name of that tune. Well, for those buying the new iPod Nano, that's an inconvenience of the past. Apple's new iTunes Tagging allows you to see the metadata pertaining to that tune and allows you to tag it so that when you get home, the tunes information is simply sitting in a file on iTunes ready for you to review and buy it. Tagging is simply a click of the iPod's click wheel. Apple's latest feature has been in the works at Apple for years. Apple finally executing on this feature fulfills one of their 2008 patent applications which richly details the advances of tagging and where it could be going in the bigger scheme of things.
