Why is this in the computer section? Because it has to do with the increasing digitization of music. Here's my opinion, and I have to admit, I'm only guessing: Walmart, Target, and other chain retailers need to be looking ahead to how they're going to replace CD sales (if they aren't already). The person who comes up with the kiosk that you can pay 99 cents, attach your phone or MP3 player, and download the song (similar to a Redbox rental kiosk), might be tapping into the market....but as the article says, the person who can crack the revenue stream puzzle for streaming music is going to walk away with a ton of money. I'm surprised that I haven't seen "gift cards" for Pandora or Spotify, or other streaming music apps...or maybe I haven't been paying attention.
