You may note I inserted a series of asterisks in your quote. Gordon, I am not picking on you, I am just fed up with that word. I am posting my thoughts on it on a new post.
Actually, I thought about what to call the music quite a bit before I called it that. It's not "American" music, per se, because a lot of it is British (etc.), and countries south of the US/Mexico border are also American. It's not all in English and not all music in English is it. It's not any particular genre. The word I used isn't, IMO, a pejorative, it's just the label I put on the circle of the Venn diagram of all music that encompasses the music I am talking about, and no other label I could think of is its equivalent.
Maybe it's like the "N" word; being one myself I can use it.
