Same issue with .strm and HTTP. 
I know that .strm isn't supported officially. I've just tested this case to see if it's a problem in how our path is stored in the musicdb or if the path is a http:// protocol. But it won't work for both of them.

Emby database construct:
path table: https://xx.xx.xx./emby/audio/72268/
song file: stream.mp3

Manipulated structure:
path table: %local path% as usual
song file track.strm

Btw: .strm works well for single file playback even if it's by accident
