If a song plays on HD Radio does anyone hear it? No. No one in the general public even knows, or even cares about HD radio. If I-Biqiuty smashes the price of an HD radio with I tagging, does that mean people are going to rush out to buy a monolithic receiving device to wait for a song to play on an FM sub channel, to tag it so that they can trigger their home computer to down load it on to their I-pod/I-phone, which they left at home? No. No one in the general public even knows, or even cares about HD radio. If I-Biquity gives away HD radios for free, will anyone hear it? No. No one in the general public even knows, or even cares about HD radio. If a tree falls in the forest, and it's broadcast over HD radio, does anyone hear it?
