I can easy assume the answer to this question, but on the off chance I'm wrong, I'd like to know for sure.
Is there a way to instill other sounds and music clips onto the Boombox emotes than is already available? I've taken a liking to the Pocket D dance floor rif, as short as it is, and would dig it if I could play it on my boombox. There's a few other tracks I've heard here and there in missions and out and about that are far better than some of the boombox tracks.
I've heard of how some things are adjustable in game, and that some emotes are gifted from getting badges. So I thought I'd ask, just in case there is a way.
