Possible to clear "now playing" on MS?

[jacksaturn]

Is there a curl command that a user can send to MS telling it to clear whatever is currently "Now Playing"?

My scenario:

When the final track of a playlist or album ends, my script sends a "single" scrobble for that final track to MS, then my script shuts down until I manually start another song playing.

I noticed that the track is still hanging out as "Now Playing" on MS for a few minutes after the fact, so I timed it with a stopwatch and watched the logs. My best guess was that it would be the track's length — taken from the "duration" field in the scrobble — plus a 60-second cool-down. But the time worked out to 5:30 from the moment the track was scrobbled until it was completely cleared in the MS UI (and thus on Last.fm and Listenbrainz).

There is no functionality for controlling Now Playing via the API.

Now Playing should last for the duration reported for the scrobble/playing_now submit-listen. This was a feature implemented in the last release. If it's lasting much longer than necessary that is a bug I need to fix.
