How do people create platform-agnostic mixtapes these days?

It's the first time I'm doing this in the streaming age. Last "mixtape" I got was a screenshot of an Apple Music playlist, which I then recreated in another streaming service.

I mean the whole point is to put a little effort into it, so I'm thinking:

- build the playlist on streaming service
- buy each song and download
- rename MP3s in order
- upload to personal site
- maybe add a nice HTML player? make each track downloadable? zip them all? idk this is getting complicated
- send her the URL

Thoughts?

Steps 1-3 complete. I held off on code as long as possible. I'm now writing a basic static site generator for this mixtape 😄

Also a blog post is expected.
