I don't think that producers are trying to disrespect the public. I think they themselves are not very bright if it makes sense to them. They are trying to come up fast with something catchy, not necessarily something that's thought through from beginning to end, but something that will sell and get a lot of attention quickly. There's a lot of stupid crap out there in terms of words not making sense, facts used in wrong ways and conflicting storylines in pop music and hollywood movies, and when I see something not making sense, it usually annoys me too. However, if I like music more than words, I would filter out the latter, and just listen to the music and disregard the part that doesn't really makes sense to me, or if I really like the piece, I will try to make sense of it, just for my own sake. I guess, it's more about appealing to the heart than the brain.
The music industry, as well as the movie industry have become very sloppy, and I don't think that the producers are trying to be maliciously disrespecting the audience, I think they themselves are shallow for thinking that the audience will eat everything and not question the meaning. Lately, it's more about superficiality than depth, as sad as it may be. I don't think producers are to blaim, because if something sells, they know they hit something, and that's how they make their assumptions, because they are in business for the money. And as we know, a lot of shit sells nowadays (I'm talking more about movie industry than the music one).
