Interesting man. I think as the world becomes smaller at a faster rate, we are seeing a BIG transition to more and more fusion. Culture (containing art, music, language, ...) has always been a result of fusion. It's getting harder and harder to create a new 'genre' - because all the genres are here already, and thanks to the internet things are mixing up.
I believe in subgenres though! Like the subgenre in hiphop perfected by the likes of Kanye West, Kid Cudi, Drake, ... lyrical, emotional, spiritual, personal, real life stuff.
It feels like every big artist has to be their own genre now. Each flow is like a genre, the Kendrick thing, the Pump thing, for a minute everyone was talking about Young Thug's vocal weirdness, etc.
I'm with you mate, lyrics are important. I was impressed by the Cardi B album for bringing that element to the fore while being fun as hell in the process.
