New Songs

Hey!

First of all, congratulations for the project!
It's nicely documented and the infrastructure is also very well organized!

Second, I would like to understand more about the process of generating songs.
I've noticed theres a song TS file at `src/shared/songs.ts`, but when I've opened the file, like this one:

I saw the actual audio and video are baked into the same video file.
What would be process if I would like for example to turn more songs into video files like this one?

Start by reading src/shared/songs.ts and the existing project documentation to identify how song entries reference their media files. Document the process for turning a song into a video file like the linked example, including the required inputs and where the resulting file is registered.
