Excerpts from TidBITS’ review on song tagging:
“I tuned through some commercial stations, saw the Tag button light up after a digital broadcast had locked in – it can take 5 to 8 seconds for locking, although analog plays on an AM or HD1 on FM while you wait. I tapped Tag, saw that tagging information was being synced to my iPhone, and that was that.
Later, I brought the iPhone inside, popped it in its dock to charge, and the Tagging item showed up in the sidebar in iTunes…
For instance, you’re tooling down the road at 12:34 PM listening to a particularly fascinating discussion on NPR’s “Talk of the Nation.” What if the Tag button linked to the future podcast download of what you’re hearing?
You get out of your car 15 minutes later and walk into your office, missing the last part of the program, and when the Wi-Fi network kicks in after 1:00 PM, the program starts to download. Perhaps you’re even alerted that it’s available – and perhaps the podcast is set to the point at which you stopped listening on the radio? All of this would be technically possible, even if a bit of cleverness were required.”
