Full circle?
So we're back to the new equivalent of radio stations... complete with ads. If I recall correctly, radio stations survive, and indeed profit, from selling advertising space between tracks.
And now the equivalent, completely customisable streaming music, is so much more tempting to people's ears - I don't blame the industry from trying to monetise this the only way it knows how, through advertising.
They'd better be quick, while there's still people who aren't sufficiently tech-savvy to know better. And while people's moral perception is still against listening to music for free (although to be fair they might be too late on this one).
To be quite honest though, the industry claiming that technology will kill music is very shortsighted. The radio didn't kill concerts, the TV didn't kill radio, the internet didn't kill newspapers, home taping didn't kill music, video didn't kill the radio star. Media formats change; public requirements change; technology changes, and commercial interests will all change to fit.
