Start by jogging your own memory. It’s easy to turn to the Internet first, but you’ll feel like you’ve achieved something if you come up with the answer on your own. Try singing the song in your head using the few words that you remember. Ask yourself whether there are any associations that are attached to this song, possibly certain people, places or a time period in your life that will help you make a connection.
Search online for lyrics that you can remember and type into a search engine “Lyrics" (the lyrics you can remember). See if any of the choices returned and listed below are the song you are looking for.
Search for the artist’s name if you know the name of the artist but not the song title. On Amazon.com, ilike.com and itunes you can preview songs before buying them. This can be a lengthy process to find a song title. You may have to scan every album an artist has, listening to snippets of each song before you recognize the song that you are looking for.
Download a song recognizer application for your mobile phone such as Midomi and Shazaam. These applications can analyze any song that you play near the speaker and will supply you with the artist, album and song title.
