Shazam is an application available for most smartphones and is used to identify songs for the user. Google's Search application for Android has a similar function. If a smartphone is not available, entering a portion of the lyrics into a Genius.com query often returns results including the name of the artist.
Shazam has been in use since 2002 and began as a phone-based service that users called to identify songs. Today the process has been streamlined into a mobile application available for iPhone, Android and Windows Phones.
In March of 2014, Google announced that an update to the Search application for Android devices features song-recognition capabilities. Now, Google's song recognition software functions largely the same as Shazam. Both Shazam and Google Search are free applications, and Google Search is pre-loaded on Android devices.
Finally, if a smartphone is not available, there are a number of websites that serve as searchable lyric databases. Among the most popular sites are Genius.com and AZLyrics.com. These websites can be used to identify songs if the user can recall a portion of the lyrics. In general, the greater the number of words searched, the more accurate the results. The lyrics do not necessarily need to be sequential; most portions of the song, regardless of sequence, helps narrow the search.
