Download a song-tagging application to your iPhone, iPod Touch, Android, BlackBerry or other mobile device. Popular examples of song tagging applications include Shazam, Midomi and MusicID. Use the "Store" or "Apps" function to search for and download an application.
Open the application. Once downloaded, the app should appear on your main menu with your other downloaded applications. Click or tap it once to open it.
Hold the mobile device near the speaker as a song plays. Click the "Tag" button, and continue to hold the device near the speaker until the tagging process concludes. The song title and album information will appear on your screen if recognized by the application.
Open the song file using a free digital media program like iTunes, MediaMonkey or Windows Media Player. These programs identify songs using ID3 tags, encoded information regarding the song title, album title, artist name and other information. These programs (and others like them) will search online databases for missing song information. Note that you must already have the song saved on your computer in order to attempt this method.
Click your "Library" heading (usually appearing in the left column or along the top of your software window). Select the song file with your mouse to highlight it. If it currently uses a generic title like "Track 1," you may need to play it first to verify that you have the correct fie.
Choose the "Search for Artist Information" option. In iTunes, you would click "Advanced" on your menu bar, and select "Get Track Names." If using Windows Media Player, right-click the song title, and select "Get Album Info." If using Media Monkey, click "Tools" on your menu bar, and select "Auto-Tag from Web."
Write down a few words or lines from the song as it plays so that you do not forget the lyrics. In most cases, a few words should suffice. If you do not have the song file on your computer, and you do not have a song tagging application, this method may be your only option.
Enter the lyrics into your favorite search engine, such as Google, Bing or Yahoo! and perform a basic search. If the song is fairly well known, you should see a variety of lyrics websites at the top of your search results.
