I'll tell you what I call it: Pop Dance.
It's been around for decades, yet it changes over time. It is made quickly, usually in a few weeks.
It always sells more than the 'underground' variety because it has the catchy melodies and snappy synthesizers.
There is almost never a story or meaning in the music, totally mindless. You can find it all over the world, with a history of sales, distribution is widespread.
