Ok, your second paragraph puts this a little more in perspective. I think you need to do a better job of communicating that. It may help to have a videos showing how it works.

This would actually be ideal on something like the Apple TV (which doesn't have apps yet but my bet is that it will at some point). Look into what's happening with Apple's upcoming AirPlay.

Other set top boxes could be adapted for this. Roku, Boxee, Google TV. That sort of thing.

So what you need is:

1. Apps for the set top boxes;

2. Apps for Android and iOS; and

3. Facebook apps.

(2) is really really important. You need something so someone can pick a song on their iPhone and "queue it up" on your party.

The app running on the set top box would record what was played and publish it. If songs are skipped then don't include them. This way it's more of a living, breathing playlist.

I guess this part goes to social media integration: publish that list to Facebook. It might be useful if someone says "What was that song at the party last night?".

But don't underestimate the importance of a good app for the people at the: to say what's playing and make requests. Think of it like an interactive, distributed jukebox.

And there's an idea for making money from it: iTunes affiliate links to the songs played.
