Where exactly are music files stored?

Apparently the conversion from the iTunes.app to the Music.app didn't go very smooth on my system.

I ended up with two sets of music:

User/Home/Music/iTunes/iTunes Music/Music and User/Home/Music/Music/Media/Music

I reset the location in the Music.app which gave me User/Home/Music/Music/Media but I'm still unsure if the music files themselves are in the Media folder or in another nested Music folder. Adding to the confusion, in the Media folder there are three folders (Music, Automatically Add to Music, Downloads-Music) and a file, Music Library.musiclibrary. Any help as to what goes where would be much appreciated.
