My Question or Issue

**Sighs***

I have read so many solutions to this and for me NONE have worked. 

I'm using the Spotify Desktop App and I cannot ......CANNOT remove any local files, making 6000 Songs unplayable. 

I had to save space on my Mac so I removed all the music & all iTunes and no, I will not be re-adding them. 

I have tried:  

- Unticking 'Local Files Source' in Settings

- Adding a new Local File Source  (this just adds and doesn't replace, I now have 6,050 Songs)

- Deleting every Cache/History,

- Deleting every BNK File, every Spotify related file in Library, C-Drive, HardDrive etc 

- Emptying the trash, uninstalling app and restarting Mac.  

- Reinstalled the App Serval times. 

Nothing has worked.

Send help or at least at the option to delete local files in next app update.
