It would be nice to hear a few bars at the beginning to show how it all comes together and then let the me go at it from there.
I also think, this would be a great bar game that could be played on the now ubiquitous smart-tv's as a counterpoint to karaoke.
Basically you pull up Rap Coach on any device, enter party mode, and then a party URL is displayed on the interface. Anyone can go to that URL and pick a beat and topic and add it to the playlist. At the end of each song it announces the next person.
So kinda like karaoke without needing a KJ. We're planning to host live Rap Coach events once that's in place.
