sp is a command-line client for Spotify's dbus interface. Play, pause, skip and search tracks from the comfort of your command line. Included mustream to do spotify search, revising the outdated cUrl search from the original sp code.

sp

#!/usr/bin/env bash

#
# This is sp, the command-line Spotify controller. It talks to a running
# instance of the Spotify Linux client over dbus, providing an interface not
# unlike mpc.
#
# Put differently, it allows you to control Spotify without leaving the comfort
# of your command line, and without a custom client or Premium subscription.
#
# As an added bonus, it also works with ssh, at and cron.
#
# Example:
# $ sp weather girls raining men
# $ sp current
# Album   100 Hits Of The '80s
# Artist  The Weather Girls
# Title   It's Raining Men
# $ sp pause
#
# Alarm clock example:
# $ at 7:45 <<< 'sp bangarang'
#
# Remote example:
# $ ssh [email protected] 'sp imperial march'
