Spotify was founded in April 2006 and official release was October 2008, after that it took time to build up the userbase. If you look at Voxxo, it is much more complex, because they have bigger plans. So I guess it will take a lot more time before we see a working platform
Rushing is a very bad idea. Spotify took their time and if you look today they are now one of the most know companies in the world. I think that Voxxo will also need a long time to get known. They maybe have bigger plans, but it will be nothing if they can't have users using it.
