Clear Channel has hooked up with Apple in a deal to "tag" the tunes played on its HD digital stations in a way that lets listeners ID and buy the tracks from iTunes, Bloomberg reports. They can also push a button to add songs to their iPod playlists.

The tags have been added to more than 345 of Clear Channel's HD digital stations.

According to the Bloomberg article, listeners need an HD radio with an iPod docking station to take advantage of the service.
