Adding sound to the web

It seems that one of the big trends today is in adding sound to web sites. A couple of weeks back I tried Sonific's widget for adding music to blogs (on the right-hand side bar of this blog); I actually like Sonific's model a lot and I think the company has a great asset in Gerd Leonhard. Today I came across a service called Razz. What I really like about Razz is that it provides for reuse of digital
content, which I think is a key feature of web 2.0 services: it is read
and write. In a matter of minutes I was able to upload a sound file (a song I got from a band on Jamendo) and to mix it with recordings that were available on Razz... Now, I don't claim any artistic quality for this, but it is an example of some interesting initiatives out there..

Make your own Razz!

My questions:

1. how is Razz going to make money? I can see a couple of ways, but since I have no idea of their business strategy and business model it's a tough call;



2. is this a venture that will actually generate over 100 million US dollars within 5 years? It seems Guy Kawasaki thinks so... which is interesting
