i had an apple music playlist i wanted to share with my students. sharing a youtube playlist sounded easier than sending people files, but i didn't want to manually search up every single song.

so, to save time (spoiler: i did not save time), i wrote a script that goes through the playlist and searches youtube for each song automatically. i ended up with a list of youtube urls that was actually kinda reliable.

"what if i just render these in a youtube iframe, and structure everything as tandas instead of a flat list of songs?"

youtube's api has strict limits you can't get around without paying, so a real playlist was out. but i had the urls, so i built a quick little player. since i controlled the whole thing, i could group everything into tandas.

over time i filled the database with recordings that already have youtube urls attached. now when you build a tanda, the recordings just show up. most of them, anyway. and if something's missing, you can add it yourself.

i thought it would be cool to have a list of musical properties with lots of examples i could quickly share with people.

i figured out how to make targeted little snippets, exact moments that show a concept, with a loop button so you can sit with a sample and really hear it.

i also added a way to compare the same tango recorded by different orchestras, side by side, so you can just listen to how they each approach it.
