Hard to believe it but iTunes tagging has finally arrived in Europe. Well, Great Britain. The UK? Fine, England. Ok, ok, to those parts of London where you can tune into Absolute Radio 105.8FM -- the only European station to have inked a deal with Seattle-based Jump2Go (developer of the tech) and Britain's own Unique Interactive. Owners of the new iPod nano with built-in FM radio can now tag songs they're listening to for later purchase from the iTunes store when docked. Video demonstration after the break for you London newbs.
