Funny, you can tell by which generation/culture a player was made based on the listed genres. In this case I see acid jazz, trip-hop, and moombahton but no dubstep or glitch hop.
I'm playing Electro House right now. There's also Electronic, House, and Techno. You can't really judge them for not bothering to list every subcategory.
Not saying they must list every one. Rather it's always interesting / fun too see to see when someone releases a player w/ genres which ones they'll offer.
