Though POPulair with a wide audience, songs that can be rinsed and repeated often are not considered unique, I think that is what people get opinionated over. That does not mean that the people that bash pop music have good taste either. (often it is just the pop music from a few decades earlier)
You cant argue taste, everyone likes what makes them happy. Personally I like real artists that dont do it for the money, but put soul in their (self written) work, and go from pub to pub to play, just for passion. It is a rare thing, but they excist. More in some genres than others.
I guess music that is about the music, something the artist would play in his livingroom even if there was no audience (or money) just their love for the guitar for instance. Barely anything on the radio qualifies for that. (logically cause those are usually pushed by record labels/managers)
The above is my personal opionion and taste, people that like other stuff arent any less. Though there is a bigger chance of a click with people that have the same interest
