Long pause when starting or skipping songs

[Manlibear]

When I start playing or a song or skip there is a long pause (around 10 seconds), here is the log from the time:

I can confirm that I also get long delays and log messages - I clearly remember this:

plugin.audio.spotify --> b'WHOOPS!!! Running spotty still handling same request - leave it alone.'

The message confused me/made me think that playback on the new song is not started because:

1. either the plugin is looking whether the previous one has finished a bit too early or
2. the previous playback takes long to clean up after sound already has long ceased.

But I didn't dig deep enough yet to figure out what it really means.

This happens, when in plugin access /track url, spotty binary is running, it has track_id and range variables filled in. It happens to me sometimes too. When i try to wget url from log, it downloads PCM file, without problems.

This happens almost everytime, i try to control kodi remotely using yatse, it does not happen often when i use keyboard to control plugin locally (i want to close this kodi to closet and control it remotely)
