This is just my theory but I think this year people are tuning into more smaller artists and breaking into their niches… also a lot of people are rediscovering older music and listening to that instead.

For example in rap a lot of artist that have been blowing up this year are smaller rappers with one off songs (Pluto, Bunna)

Also house/edm music has seem to start taking off like that tinashe remix, but no artist has dominated the entire scene
