I dunno, Pop music seems more of a marketing gimmick than a musical genre.
Grab a simple enough theme to relate to as wide an audience as possible.
Add a catchy beat and lyrics sung by a charismatic performer.
Throw in some glitz and glitter and bam, hit single.
Now, don't get me wrong, pop music isn't all bad, and I listen to a bit of it myself, but alas, I still don't feel like packaging cheap ideas in shiny music and shipping it out for maximum profits has much integrity or standing as an art form. (I get that companies need to make money, but I feel that pop music is like mass producing a bunch of cheap products as opposed to dedicating time into a really refined outcome. It seems to be putting profits before actual music, imo.)
you just described rock, rap, alternative rock, indie rock, folk, hip-hop, metal etc.
