I recently joined Spotify as a free user in the U. S. They are just now rolling out in the States. Apparently, in the next six months, the REAL model (not free) will be pushed even harder. Still not a bad deal. I will have to think about whether this should be a fee based or advertiser based plan. Remember when cable cost, but there were no adertisements. Things do change, don't they? And the music business is the midst of extreme change right now.
I get to witness this from both directions because I'm also an artist on Spotify and rather proud of my 1/10th of a cent spins! :-)
