If you hear a song in a YouTube video, but the description doesn't mention the song's title, you can identify the song using software or by asking someone who can help. Other YouTube users probably also want to identify the song, and they often post their questions and answers in the comments section. Several websites and mobile apps provide music identification services, and many online lyrics databases return search results based on the lyrics.
Find Information on the Video Page
Select the "About" tab on the video's YouTube page and click "Show More" to read the video description. The video uploader may include the song title and link to buy the song in the description.
Read the comments to see if other YouTube users know the song title. If the video receives a lot of views, you may quickly get your answer by posting a question in the comments section. If you don't have a YouTube or Google+ account, you will be prompted to create one before posting your comment or question.
Contact the video uploader directly by clicking the uploader's name, selecting the "About" tab and clicking "Send Message." In your message, be as specific as possible, and remember to provide the name of the video.
Online Music Identification Services
Download the YouTube video in MP3 format by visiting a site such as YouTube MP3, Vid to MP3 or Video2MP3 (links in Resources). Enter the video URL in the text field and click "Convert" to receive a download link to the new MP3 file.
Visit a website such as AudioTag, LyricFind or Midomi (links in Resources). These sites enable you to find unknown song titles by uploading an MP3, searching for lyrics or humming a melody, respectively.
Click "Browse" on the AudioTag site to upload the MP3. The process takes two to three minutes, depending on the file size, and if successful, it displays the song title. If it doesn't succeed, you must try another method.
Enter song lyrics in the LyricFind search field. The search engine immediately returns the most relevant results, and the first result is probably the song you're searching for.
Connect a microphone to your computer, select "Click and Sing or Hum" on the Midomi site and then sing or hum the melody. The service works best if you provide at least 10 seconds of the melody, but if you don't know that much, you can try repeating the melody that you do know. If the search succeeds, Midomi displays your song title on the next page.
Install a mobile app such as Shazam, SoundHound or SpotSearch (links in Resources). With Shazam, you can hold your phone near your computer to record and identify the song. SoundHound enables you to hum or sing a melody, and SpotSearch matches song titles based on a lyrics search.
Play the YouTube video on your computer, tap the Shazam screen and hold your phone near your computer speakers for 10 to 20 seconds, or as long as the song plays. If Shazam succeeds, it displays the song title and artist.
Tap "What's That Song" on the SoundHound screen and sing or hum about 10 seconds of the song. If SoundHound can identify the music, it displays the song's title and information.
Enter lyrics in the SpotSearch search box and tap "Find the Song." The app returns results similar to LyricFind, but SpotSearch is based on the Spotify music database. Since it's only available for Android, if you have an iOS or Windows device, you must use the Web-based SpotSearch app, available from the download page.
