Question on adding and playing inline music videos.

I have gone through the docs support.plex.tv/hc/en-us/articles/205568377-Adding-Local-Artist-and-Music-Videos

My music track is

Album Name - track# - track name.mp3

and the video track is:

Album Name - track# - track name-video.mp4

So what’s supposed to happen now? I have rescanned the library, but I don’t see the videos in the track list.

Can anyone tell what I’m doing wrong with music videos?
