@EpicSteve: There are. Or rather there have been in shows like Retronauts. But the Bombcrew seem to hold many opinions in contrast to the standard fare that I think a music episode could be very interesting.
what you say may be true but just think of the hijinks that could be had in J,R, and V being free to delve deep into their pasts as videogame enthusiasts and beguiling us with tales of yore. So maybe an episode where they are not required to talk just about recent games but their favorite game experiences of all time or whatever.
I believe a universal language would be extremely beneficial to the state of the world over. I think with the rapid expansion of information/communication technology will make this an inevitability anyway. I also believe the strife caused by lingual/cultural barriers much outweigh their value. This could get us one step closer to everybody realizing that we're all in this together.
