I was disappointed that they broke up GTA V's pop station to have music from all decades. I would prefer if it was either only modern or only classic. Going from 2012 Britney Spears to a 90's dance song is ugh.
I also was hoping there would be a "modern rock" station. Like one that has stuff from the early 90's grunge scene, some stuff from the 70's and newer stuff (though tasteful, no theory of a dead man or nickleback or shinedown)
Classic rock stations have disappointed as of late. It's as if they used all of the good songs they could think of on K-DST and everything since for the most part is secondary and tertiary stuff.
GTA 6 needs a j-pop station, a decent classic rock station that rivals kdst, more classical music or big band swing, and some world music akin to radio del mundo on LCS.
