This article has already raised a few eyebrows. No wonder, because it IS a pretty bad idea, ruining (what I see as) the entire concept of Myspace. The only obvious conclusion will be that artists, fans and bloggers will start searching for and very soon find alternative ways to promote and get free music.
Another thing upsetting several bloggers is that Myspace has reduced the bit rate of all songs to 96 Kbps, thus ruining the listening pleasure for everyone.
Of course all this has been decided with some strategic purpose in mind, and with more than 100 million users they can easily afford the number to be reduced, as long as those left (still counting millions) are willing to spend a little cash (which I don't doubt they will).
But the quest for alternatives has certainly begun!
