I'd be interested in something that was the web site equivalent of Spotify, but not if it was HTML HBO. I think the reason the online music subscriptions have done so well is that their catalogs span multiple publishers, and customers really don't want to subscribe to multiple services. While there's minor differences, you pretty much can get access to any music you can think of. Otherwise you just end up with some crummy bundling service where you pay a premium for a few things you are interested in, and waste money on the rest of the junk.
