I've already added the music folders on the external drive as media sources in Kodi and can play music from the Music Homes Screen.
But I want to play music from playlists in Kodi/userdata/music/playlists/jazz.m3u (for example)
However, playlists point to external drive.
So how do I make playlists point to Kodi.
Please explain alternatives to the following playlist -
#EXTM3U
#EXTINF:300,Dream A Little Dream Of Me - Ella Fitzgerald
/Volumes/1.MacDOCS/Music/_iTunes/iTunes Media/Music/Ella Fitzgerald/All That Jazz/01 Dream A Little Dream Of Me.m4a
With what do I replace the first part of the path that points to the external drive? -  
/Volumes/1.MacDOCS/Music/_iTunes/iTunes Media/ ?
Music folder in last part of path is the media source folder that's been added to Kodi - 
/Music/Ella Fitzgerald/All That Jazz/01 Dream A Little Dream Of Me.m4a
