Before we started building, we defined two criteria that separate the good Facebook apps from the rest. First, the app doesn't take up a lot of space and second, it’s easy to use and share.

So with those in mind, we came up with four Facebook applications that would tie-in with our primary business model, creating professional digital audio.

Voices.com's Facebook Player

Let's jump to it.
