Tommy Brown (TBHits) and NMIXX in the documentary trailer?

I just noticed the inclusion of the Champagne Therapy Music Group(Tommy Brown's label) logo in the documentary trailer. I had completely forgotten they had met up 9 months ago. I know that he's not credited on any of the songs on this album, but seeing as they're choosing to include footage of the meeting do you guys think there might be a song they're saving for a future release?

I guess I could just wait for the documentary to come out for more info, but I'm super curious.
