Back Story: Our team has drastically different tastes in music and constantly debates which song to play on the office stereo. By creating a web-based, Go-powered social jukebox, now we can argue about the horrible taste of our coworkers at high scale! This is a distributed application with 3 core components:

Angular.js single-page UI app
Go + applescript "remote" that puppets the Spotify binary
Go API endpoint that manages the shared queue and brokers connections between clients

Inspiration: We were inspired by the fun and simplicity of Go, the ease of use of the Spotify API, and a desire to make fun of each others' musical preferences.

Target user: anyone who works in teams and has ears.
