I'm quite aware of how songs are written, I started my life as music major in undergrad... so I'm pretty sure I know much more than you could ever imagine about music, music theory and how songs are written. There is no evidence that the one song came from another.I don’t think you understand how songs are written. It would be like, they need a song that would sound like something of the era of Reconstruction or before. They see this song and take from “Zip-a-Duden” and give it their own spin to avoid straight up plagiarism. They put a happy spin on it because that’s what they’re trying to do. They may even be trying to take something bad and make something good out of it.
But my point is simply people don’t generally use that terminology by happy coincidence and it makes perfect sense in the context of having to write a song for the movie.
You can give them bonus points if you think they were trying to make something good out of something bad. If that makes you feel better. But that’s what this ride was also trying to do.
Your problem is that like all the other woke warriors you went out looking to find a connection to slavery and racism and guess what... if you look for something hard enough you'll manage to convince yourself that something exist when the fact is it is only in our imagination. There has NEVER been any real evidence that lyricist of the song ever heard of the other one. Do you honestly think a guy from Connecticut that moved to California is going to have come into contact with racially charged songs from the Deep South?
There are things known as coincidence and when you have the words, "zip" and "day" in two songs that is hardly proof that one sprang from the other. Frankly the word day is so common you really can't include that so you have one unique word, "zip" used in two songs, the reality is your mind is not going to be changed because you want to believe that a person is guilty until proven innocent. I prefer to believe a person is innocent until proven guilty. So go ahead and condemn people with no evidence, and just pray no one does the same to you.
