Just out of interest, did you get a copyright claim on your video for using this?
For my first drone video I used a track from what I thought was a rather obscure ambient artist, but YT still picked it up and put in a copyright claim. While in practical terms this just means I can’t “monetize” the video (which I wouldn’t anyway) I decided to re-render the video with my own soundtrack.
If anyone is interested in keeping full control of their videos on YouTube, check out this thread for royalty-free background music.
