I was creating a playlist on Spotify, going through pages of artists adding a few songs from one artist, a few songs from the next artist and so on. But I didn't want the playlist to look like this.
So I checked if Spotify had an API and they did. So I started writing Spotify Shuffler to shuffle my playlists.
Since I wanted to learn Vue.js anyway, I decided to use it as my JS Framework.
I finished a first rough version and then lost interest in pursuing it further.
