#!/bin/sh

# A dwm_bar function that shows the current artist, track, duration, and status from Spotify using playerctl
# Joe Standring <git@joestandring.com>
# GNU GPLv3

# Dependencies: spotify/spotifyd, playerctl

# NOTE: The official spotify client does not provide the track position or shuffle status through playerctl. This does work through spotifyd however.
