Most of the music I have purchased in the recent past came from artists I first heard on Internet radio.
The local AM/FM stations here seem to have playlists of less than 250 songs that repeat over and over and over and over. I liked most of them the first thousand times or so.
XM is a little better as they seem to change the songs with the changing seasons.
As it stands now, based on the information in the article, all we will be left with is Internet broadcasts of traditional AM/FM stations. Wake me up for lunch.
