I want Spotify to do well, but the reason I'm cautious is the lack of true differentiation. Spotify has a great platform, but I'd worry about the level of control that the labels and artists have over their catalog, and the fact that they make a lot of money as a middleman between consumers and artists... I just feel like I could see another company coming and eating their lunch relatively easily. They're not like Netflix, who has differentiated themselves with exclusive content.

But I REALLY hope they succeed, because I've been a customer since they first announced US support.
