Incomplete Local Files List

[Iceburg]

Spotify shows that I have 24,808 songs in my Local Files list. However, when I completely scroll down the list, it just cuts off amidst the "S" part of the directory. No songs show up, alphabetically, past "So..." in the list.
I know I have songs that start with T - Z. Why does my entire list not show up in local files? Is there a limit to the amount of local files the software can reference at any time? If so, please advise. I would prefer a local file player that actually looks at all of the referenced files and shows a complete list. If organized by artist, it only goes as far as They Might Be Giants.
