Lots of things wrong with the industry, but this isn't one of them. Bands get big because they attract/entice a large audience with marketable music that is simple minded, and occasionally abstract. If you can honestly say that Circa Survive, for arguments sake, would fit on mainstream radio, you're out of your mind. That's not to say the band isn't "good," just that sometimes they're more fitting to a nitche audience. Same goes for pop artists, being simple and easily accessible doesn't make you "bad." Both parties know what they're doing and what their goals are and how big they realistically think they can be.
No, Circa wouldn't fit anymore (although they are played on XM/Sirius quite a bit, FYI), but at one time they would have (look back in time to the 60s and 70s), maybe not them exactly, but you get what I am saying (bands with musicians who care more about depth then record sales). Like I said with someone else, it isn't the business, it's the society accepting mindless music with no depth anymore, it's really sad. But, too each, their own. I actually do think the song is kind of catchy (more so acoustically with just Adam), but whatever. Sorry to offend you.
But if you say Circa has a "niche" audience...that is one HUGE niche, considering they have 360+ thousand fans on facebook...sell out just about every venue they go to, and are constantly gaining new fans...food for thought :)
