Okay, RJ sent The Deadstation 100%. I'm sure he's the only one who knows about it. Which means IQ is Mason's.
Wonder who sent Need... probably Train of Naught, I sent him Orvam in his roulette. Bummer, I planned to use them in future rounds.
I'm guessing Parama sent TesseracT then, he likes djent.
Gotta say, it's once again a very-RJ-like list of bands. Guess it happens when you introduce a lot of awesome music to almost everyone on board.
