I don't disparage people's tastes because they aren't schooled in music, like simple songs, like popular music, etc. I disparage them because it is limited to such a small sample of 3 songs that get requested over and over again. And the funny thing is that I often ask what people's favorite songs are, and in decades NOT A SINGLE ONE has ever said Mustang Sally, Sweet Home Alabama, or Brown Eyed Girl. I do wedding gigs where the client pays thousands of dollars to hear their favorite songs and not one of them has requested one of those. I would love to play their favorite song, but often people don't ask for it. Sometimes I feel like people request these songs out of habit, or because most bands know it, not because it's one of their favorite songs.
I come to party and play music too, and like I said before, my musical standards are really not that high at all. But, that doesn't mean that I'm not disappointed when the same 3 songs get requested again and again when there's so much other fun music out there. I don't think there's anything elitist in that. If anything, if one's taste is limited to 3 tunes, it sure can't hurt to broaden it.
