It's not all mindless. There are some genuinely good pop artists out there. I won't mention any, because I don't want to derail the conversation, but many of them write their own music, produce it, or at least have a hand in it other than singing it. Society accepted fun., and I don't think that many on this site would label them as "mindless."
And "niche" doesn't mean garage band. Circa Survive is on a well known label and has played many tours, sold out shows and so forth...what I meant by niche was that they find their place in the music industry and cater to it. They don't try to get on the radio. They just make their music and let what happens, happen. What I meant was that Circa Survive would never follow Taylor Swift or Gaga on the radio, because it's an obscure sound by means of comparison. Pop radio has a flow and play similar music that is made with "pop" in mind. So to say "Band (x) deserves to be more popular" or "Band (x) deserves to get more radio play," you're forgetting a large part that what makes them able to make the music they make is not being on the radio. If they were to get on the radio, they'd have to reform themselves musically, marketing, image, etc.
Sorry, just a pet peeve of mine to see people say "This band deserves to be huge," because, more than likely if they were "huge," they'd have to/probably would sound like the very music that people are dismissing. So, saying "Can't believe Owl City is on the radio, Circa Survive deserves it more," for example, assuming they did play CS on the radio rather than OC, I highly doubt CS would get more fans. People just wouldn't trust radio's judgment. People go to the radio because they like upbeat, fun music, or overly dramatic music, not necessarily because it's always simple-minded or easily accessible. Creating a melody that sticks in one's head or is layered with several harmonies or whatever can be just as difficult as what some bands do in the studio. Music that's on the radio gets waaaay too harsh treatment to people who think they know better.
