Thanks so much for the kind words! I agree the minor 4 is so goated, it pulls on those heartstrings so much.
For the wavy texture in the background I made a fog volume in Blender and keyframed the texture being rotated while the camera was in the middle, and that's it! it ended up being pretty simple even though I have very little experience in Blender:
The music player itself I custom made a little while ago so I was able to reuse that and add in the background video thankfully.
