iOS users with Siri-enabled devices can now access LyricFind's database of over 2,000 music publishers. Siri learned its new trick after Wolfram|Alpha teamed up LyricFind to add a new lyric query option to its search engine. The new service also allows Wolfram|Alpha users to create word clouds of popular terms used in a certain song. However, this feature does not seem to work on Siri at the moment.
iOS users can get the lyrics to almost any popular song by opening Siri and asking “What are the lyrics to (song title)". For some reason completing this task seems to take Siri longer than usual, and it will also refer you back to the web if it can't locate a title in LyricFind's library.
LyricFind has licences with all the major music labels including EMI Music Publishing, Universal Music Publishing Group, Warner/Chappell Music Publishing, and Sony/ATV Music Publishing, so Siri should be able to find most songs when asked. However, the voice assistant did seem to have a problem finding the lyrics to more modern music like Miley Cyrus, but had no problems locating the words for older songs like Michael Jackson's Thriller.
