Joe: There is someone credited in that video under the name "Joe A. Rider" (see https://vimeo.com/254928853) at 19:41 and 20:09. I didn't see a composer credit for him, though -- just a cast credit and two soundtrack credits.
I suggest that you watch that video and submit corrections to IMDb for whatever credits on it are incorrect. You can include as part of your explanation, where relevant, something like this: "I am Joe Rider, but I did not work on this film. The person credited on this film is a different person who goes by the name Joe A. Rider."
