Wow, I'm always amazed by the number of people who don't know about Allmusic. I've used the site for at least 7 years (for several school reports as well), and have told everyone I know about it. I don't think they advertise at all, which is odd.

Frankly, I'm amazed they've stayed free all this time. I can't imagine they make enough sales from their hard copy books, especially when the same info is available for free and more up to date. I also haven't seen it used in many business applications other than the bookstore I previously mentioned.

I agree about the UBL. Like I said, it was much better before Artistdirect turned it into a small feature of a music store of its own.
