How can I find the name of a song that is used in a YouTube video?

To find the name of a song used in a YouTube video, check the video description, as creators often credit the music there. You can also look for comments from viewers who may have identified the song. Additionally, using music identification apps like Shazam while playing the video can help you find the song. Finally, if all else fails, you can search for the video's content on social media platforms or forums where users discuss the music.
