The steps to remove background music from songs are as follows:

1. Download and open the AVSVideoEditor software on your computer.

2. Click the file in the upper left corner and select Import Media.

3. Select the file you need from the computer folder and open it.

4. At this time, the file is imported into the software.

5. The green part below represents the background music.

6. Right-click the audio track and select Mute.

7. You can see that there is an additional crossed-out speaker on the current track, which means the muting is successful. At this time, the built-in background music has been successfully eliminated.
