Found a song you want to listen to over and over again? With a few taps, you can have the iPod Touch play songs over and over again. If you have a newer iPod Touch, use Siri to repeat the last played song with one touch of a button. The process for setting a song to repeat depends on the iOS version on your device.
Steps
Method 1 of 2: iOS 7 or higher

Step 1. Go to the "Music" application and click on the "Playing now" option
If music is playing in the background, you should go to the Music app and open the Now Playing window.

Step 2. Click on the "Repeat" button, which is located in the lower left corner
This will open the repeat menu.

Step 3. Choose a repeat method
In this menu, you will have three options:
- Disable Replay: This will disable replay if enabled.
- Repeat Song: This will repeat the playback of the current song.
- Repeat All: This will enable you to repeat the entire current list, be it a playlist, album or artist.

Step 4. Use Siri to repeat the song (5th generation and up)
You can use Siri to replay songs without going into the app.
- Press and hold the Home button until Siri appears.
- Tell her, “Siri, play it again,” and the program will repeat the last song.
Method 2 of 2: iOS 6 and below

Step 1. Go to the "Music" application and click on the "Now Playing" option
You can set the song repeat function only in the "Music" application. If you're using another app and music is playing in the background, go to the Music app.

Step 2. Click on the album picture if you don't see the controls
After you open the Now Playing window, chances are the music controls won't appear on the screen. Click on the album picture to display the controls.

Step 3. Find the redo button
It looks like two arrows in a loop and is located in the lower left corner of the music controls window.

Step 4. Press once on the "Repeat" button
The number "1" will appear on the button. It indicates that the current song is being repeated.

Step 5. Press the button again to repeat the entire list
The button will be highlighted, but there will be no number on it. This indicates that the current playlist, album or artist will be played again.

Step 6. Use Siri to repeat the song (5th generation and below)
Siri can quickly repeat the last song. If you have a fifth generation iPod Touch or earlier, use simple commands to repeat the last song played.
- Press and hold the Home button until the Siri interface appears.
- Say "Repeat Again" to repeat the last song.
