How to delete duplicated songs all at one time? ― Asked by an iTunes 12 user

One of the frequently asked questions asked by iTunes users is how to mass delete duplicates in iTunes all at once. Duplicate songs and duplicate playlists are among the most common iTunes problems. It can be rather annoying if every song plays twice before it gets to the next song. iTunes’ Show Duplicate Items feature is of little help when it comes to a large number of duplicates. The good news is you can easily find and mass delete duplicates in iTunes in one go. This article will show you how.

How to show duplicates in iTunes manually

This method is for you if you:

  • Only have a few duplicate tracks in iTunes
  • Don’t want to install an iTunes duplicate finder

And you can find and delete duplicates in iTunes library manually. This option is the most tedious and time consuming and I prefer not to count it as a viable method. But there are many users who want to know the steps out there. And the detailed steps on how iTunes remove duplicates are listed as follows.

Step 1. Open the Music library in iTunes.

Step 2. Press the Alt or Option key and click the View menu.

Step 3. Select “Show Exact Duplicate Items”. This will change your list of songs to all of the duplicate tracks on your computer. These are duplicates that share the same song name, artist, and album.

Step 4. Select the duplicate songs that you want to remove. From the menu bar at the top of your computer screen, choose Edit > Delete to delete duplicate songs in iTunes.

Tip: If you don't hold the Option key, you will get the standard "Display Duplicates" option. iTunes will show duplicates based on song name, but doesn't differentiate between albums. This means that recordings and liver versions often show up as duplicates even though they aren't. Make sure you are using the newest version of iTunes on Mac. Older versions of iTunes may have the "Display Exact Duplicates" option in the File menu instead of the View menu.

Tips to stop iTunes creating duplicates

1. When you manually copy a music folder, duplicates are created. One of the easiest ways to copy a music folder to iTunes without duplicates is by adding the folder to your library. And iTunes will add any new files you place in the folder automatically without creating duplicates.

2. You can change the iTunes settings to automatically import your music without causing duplicates. Open iTunes. Select iTunes and click Preferences. Select the Advanced tab. Uncheck the option: Copy files to iTunes Media folder when adding to library.

3. The best way to prevent iTunes duplicates is to store all your music in the iTunes media folder by default. If you download music from websites other than iTunes, choose the iTunes folder as your default download folder.

4. Don’t regularly transferring purchased music from your iOS devices to iTunes.

What to do when you find duplicate songs on iPhone but not in iTunes

Another common iTunes problem is that songs are listed twice on iPhone but only once in iTunes. The following steps should fix the issue.

Step 1. Connect your iPhone to a computer with iTunes installed. Back up your iPhone. Alternatively, you can do it via iCloud. Eject your phone from iTunes.

Step 2. Go to Settings on your iPhone. Select General > Usage > Storage > Music > Edit. Tap on Delete.

Step 3. Restart your iPhone and connect it to iTunes again. Sync your iTunes playlist manually.
