Its not the right wording, but if you don't really understand why you like a song, purely in terms of the music, you will resort to "meta" reasons to like it. Like, I really really dig a bunch of Brittney Spears stuff. Apparently I'm not supposed to, because she's "big industry" and has a giant production team behind her and she's not really musically talented etc etc.
But none of that affects how "I'm a Slave" sounds to me, how much I like the break beat rythms mixed with pop vocals
Meta arguments are for people who can't talk about the music as music. It's fair you don't like a lot of pop music because you dislike 4 on the floor. It's stupid to say you don't like pop music because they are "mainstream" or because 14 year old girls like it. All saying that says is that your opinions about music have nothing to do wih music, they have to do with other, invented stuff. And the only reason someone would do that is because they don't have any real opinions about actual music.
