How to Compare USB Flash Drive Folders for Duplicate Files

I have a USB flash drive filled with thousands of MP3 song files. Some are organized within an "Artist" folder, while others are scattered in a folder called "Random." I decided to revamp my music collection by creating a "Done" folder with organized artists and albums, such as Garth Brooks' albums with complete details like album art, genre, and release year.

I am looking for an easier way to identify and remove duplicate files based on artist names or group names. Currently, I manually search for each artist in the "Random" folder to eliminate duplicates. Is there a more efficient method, perhaps a free program compatible with Windows 11, that can help streamline this process? I want to avoid having multiple copies of the same songs with incorrect file names but correct tags.

If you have any suggestions or recommendations to simplify this task, please let me know. Thank you!
