Can someone make a mash up with this movie and a Nathaniel Rateliff

This was the first movie my girlfriend and I watched together. I loved it, she hated it ha. But she didn't hate it because it was bad or to hard to understand, she just wanted the end to be "complete". Together we have now talked about this movie dozens of times and have many different theories. And even still with her "dislike" we've watched a few times because to us that is just "our movie" now. Then I hear this song from a band named Nathaniel Ratliff and the Nights Sweats with song titled 'I'd be waitin'",which is now also "our song" and ever since then iv wanted to somehow mix/mash them up into the bestimate scenes of the movie with that song in the background. If I knew how to do this I would try on my own but iv seen so many people make very great videos and hoped maybe someone would be kind enough to help me out. I would enjoy it so much and I would love to see her reaction to it. If you even took the time to read this I hope it reminds you of a great memory that fills your heart with joy.
