Repeating the same song over and over

[goose-ws]

I've got mopidy set up with the following config:

[core]
data_dir = /var/lib/mopidy
[local]
media_dir = /var/lib/mopidy/media
[audio]
output = audioresample ! audioconvert ! vorbisenc ! oggmux ! shout2send async=false mount=stream.ogg ip=icecast port=8000 password=[redacted]
[m3u]
playlists_dir = /var/lib/mopidy/playlists
[http]
hostname = 0.0.0.0
[mpd]
hostname = 0.0.0.0
[spotify]
username=[redacted]
password = [redacted]
client_id = [redacted]
client_secret = [redacted]
[gmusic]
enabled=false
[soundcloud]
enabled=false
[pandora]
enabled=false

Mopidy works, I am able to access the web interface/iris, and successfully pull up my Spotify stuff. When I play, it does stream to icecast correctly. But it only repeats whatever song I play, never moves to the next item in the queue.

For reference, here's my playback screen:

In this case, it just replays "First Dates" over and over, until I skip to the next song, at which point it ends/restarts the stream to Icecast with a new song, which it repeats over and over.

Did I configure something incorrectly?
