What is a Duplicate Music Finder?

A Duplicate Music Finder (also called, Duplicate Audio File Finder or Duplicate Song Remover) is a specialized software that helps users find duplicate songs on their computer and de-clutter their music library. It identifies them by comparing the music file tags, regardless of whether your files have the same file names or not.

Music tags are small pieces of data stored inside music files. They contain various information such as album, artist, bit rate, year, etc. You can read more about them in the User Manual.

Benefits of Using a Duplicate Song Remover

Duplicate mp3 and other files can take up a considerable storage space, and make it difficult to manage your vast collection of music. If there are too many of them, your tracks will keep on repeating.

Deleting duplicates will not only free up your storage but also make it easier to listen to your favorite songs. You can weed out low-quality duplicate versions of your music, and make space for high-quality ones. De-duping your music library will provide an enhanced music experience. You will also be able to search for your favorite song with clutter-free results, and quickly share or sync them with other people or devices.

Where Do I Get Duplicate Songs From?

  • Downloading the same songs in different audio qualities (such as higher & lower bit depth)
  • Converting music files from one format to another (for example, converting .wav files to .mp3)
  • Regular file copying activities can lead to unintended duplication
  • Transferring files from a smartphone, tablet, or other devices to your PC/ laptop

Missing Music Tags?

A question may arise in your mind, "What happens if some music files in my collection don't have music tags information?"


The answer is simple: Such files will be either skipped or the program will compare those files with other files with missing tags using a different criteria: File Content. You can change how the program reacts by configuring the program settings.

Incorrect Music Tags?

Music tags are filled by the website or store from where you downloaded your music. It is possible that they are empty or incomplete, or they are not filled correctly. In such cases, you always have the option to compare your music files using other scan modes such as "File Content + Size".


You can also edit music tags using different methods outlined in our article.
