Monterey ios Music files stored on too many iTunes and Apple Music folders

I have Monterey iOS 12.7.6 on my Mac mini 7,1.  which I moved over all the iTunes music from an old iMac.  Since then have added additional music from both downloads and cds.  As a result, the actual music files (mp3 and  m4a) are located all over the local drive.  When I use Finder to search for folders called Music, I find 4 specific folders called "Music" for example:  <username>/Music/iTunes/iTunes Music/Music/Music.  Here is the default path for adding new music:  "/Macintosh HD/Users/<user name>/Music/iTunes/iTunes Music.

Can I change this default path, then in the Music app select Organize Library - Consolidate files??  I understand this process puts a copy of the actual files in the new media folder.  I do not need to keep the old playlists, but just want all the music files in one place, where I can create new playlists and delete music I no longer need (i.e. added by my teenagers).  Or, can I use an app called Tune Sweeper to do this??  Help!!
