It certainly sounds good on the surface, but a couple of observations and questions.
At 99 cents per track, the cost is roughly the same as a CD is today. The real positive of this approach is that you don't have to pay for the tracks that you don't care for.
But some of questions that I have yet to see the answers for, and are quite related to many of the issues that we've already discussed, if you download a song a second time, do you have to pay for it again? Will you be able for free, to download a song that you've already purchased on a CD, or will you be able to download at no charge some music that you intend to buy as soon as the CD becomes available?
But I do agree guestgulkan - this is a positive direction towards music distribution.
<just kidding>
I'm quite confident that xutopia is really looking forward to this "Microsoft has indicated that it too wants to launch an online music service for its users."
Good Luck
