 That's weird. 
1) I played a song for about 30sec
2) Exit Kodi
3) Restarted Kodi
6) scanned Kodi log code to upload data using my phone
7) https://paste.kodi.tv/igiyaqutip  

Still no indication that AS is being run.  I see it listed as installed and I see the settings loaded during startup, but that's it.  Even if AS debug logging isn't on I would expect to see at least the startup message from AS in the log file when the skin calls it.  I'm going to go back to some basic questions just to make sure:

1- Are you using a skin that supports AS? If so, which one?
2- After starting the song, do you see the music visualization screen (or at least go to it manually) - that's generally when AS is called by the skin  

 1) Yes, Aura Leia
2) yes, Arist fanarst are displayed when music starts playing. But sometimes it will only show the fanart for about 20 seconds, Then I get a blank screen. 

I really do want to help, but without a log showing Artist Slideshow actually being called and doing something, there's not much else I can do.  When you get another log, do a search in it for "[artist" (without the quotes) and make sure it's case insensitive.  If AS is called, you'll get at least a few lines in the Kodi log with that prefix).  Other than that the only thing I can suggest is to contact the skin authors and see if they have any insight.
