Pop music and your opinion about it.

In general, many popular bands today had a difficult start to their careers; becoming a well-known and sought-after rock band isn't easy. For example, Linkin Park (the epitome of a pop band, right?) was rejected several times by their current label, who told them to go and do something else, but not music. And Slipknot didn't become idols overnight; you can read about it on Wikipedia. Maybe, if these bands play music that many people like, it's simply good music, not pop? Pop music is something that's made without soul, churned out like on an assembly line, doesn't carry any meaning, and tomorrow no one will remember the song that is a "hit" today. Or take some "little-known and rare" band, but what if the band is simply talentless and not really needed by anyone? (except for a very small group of ideologists who are against pop music; there will always be some). Should such a band be listened to? In general, in my opinion, you should listen to the music that you simply like, without looking at how many people listen to it; this cannot be an indicator of quality.
