You mean like this gem?
With that one statement, you just shot down every single musical ever made, and not just Disney. That's how musicals work; characters break into song spontaneously. Disney didn't invent the trend, nor are they somehow at fault for capitalizing on the fact that many people enjoy musicals. You may not like any Disney song, but lots of people love them. Everything doesn't have to be an action comic-book style thing in order to be considered good, you know. It's OK to express your opinions, but not in a way that basically belittles an entire genre just for being what it is.
