I need to first state that I'm still learning how to use Strawberry.

Next... I'm trying to make my first playlist manually. I dragged about 19 songs into a playlist and I am playing only a few seconds of each one to see if I recognize the songs (they're from a massive 80's Hits collection and I don't recognize the titles).

The problem is, I will play parts and pieces of the first 2 or 3 songs to see if I can identify them, but when I try to play the next song Strawberry hangs. If it's playing a song already then Strawberry will hang, continue playing the song I was already playing... not play the next song I clicked to play next, and the song that's playing won't be pausable or stoppable.

The beachball spins until I option-command-esc and shut down the application that way.

I don't plan on using Strawberry as a media player so it's not a huge deal.. it's just incredibly inconvenient.

I'm on a MacBook Pro 2019

Why might Strawberry only index 21k files as opposed to the 52k files I am asking it to see?

I also have Audirvana, which I was using before I decided to make the switch to Strawberry.
Audirvana sees 50,180 songs so it's clear Strawberry is missing at least a folder or 2 worth of files.

I have my settings arranged so Strawberry sees the same exact folders as Audirvana, yet Strawberry sees less than half the files Audirvana can see.

I've restarted Strawberry a number of times. I've deleted all the folders I ask Strawberry to scan and then I have re-added them all (after a reboot of Strawberry, and of my computer a couple of times).

What can I do to make Strawberry see all the files in the Music directories I am pointing it to?
