Dubstep, Electro and Ambient. With plenty of bitcrushing and dBlue glitch shit.
Top 40 music? Would be interesting and highly immersive, but only for a couple of years 8D
More interesting rap choices? Like underground rappers. Or people who spit like Busta Rhymes, a whole channel like MSX or something.`
Also I agree with classical and orchestral music. Especially if it's got that 2011-2012 sound to it.
