I have been using this service for the last two days along with a number of other coworkers at the game studio I work at. We all find it to be a wonderful service. I can't help but notice how turntable is succeeding so well in the "social music" realm (at least initially) while myspace has failed going after what would seem to be a similar demographic. It is obviously to early to tell what the outcome will be for turntable, but if I were calling the shots at myspace, I would take heed.
