We have a WhatsApp group where we share music recommendations with each other. It's grown quite a bit now and it's gotten hard to keep up. Also new members missed everything that came before. So I set out to solve this problem and have some fun last week.

I decided to write a shell script that does the following: - Parses chat export file and extracts all the Spotify URLs. - Removes duplicates - Authenticates w/ Spotify API - Fetches Ids of tracks already in playlist - Creates a difference list of missing tracks - Adds those to the playlist

And that's that.
