That is not being "ignorant", it is knowing enough about music as an art form to make an informed decision about what has a constructive (rather than a destructive) effect on the hearer, and what is timeless art rather than a disposable product made with very little actual musical knowledge or skill. That is coming from an understanding of music and what makes art and what could be considered technique (from the Greek for "art") or style. If you are capable of making an actual ARGUMENT for artstic merit in these "styles" (without resorting to the blasé anti-"elitist" OPINION), if you can make an actual argument for technical skill and learning comparable to what is expected of classical musicians (something YOU might not be informed about), or a compositional analysis that shows the artistic merit of this "music", or some empirical neurological evidence that it is healthy for you (because really it is NOT, as all the most informed ancient cultures already understood thousands of years ago), PLEASE let's hear an actual, intelligent argument rather than name-calling. Do inform me.
