The Sound Guy today announced the release of PlayLyrix, an application which searches a user’s iTunes collection and automatically creates a new playlist of all the songs whose lyrics contain specified words or phrases. PlayLyrix can be used to create playlists of songs with lyrics that reinforce a wide range of moods or themes. As an example, for a birthday party one might wish to make a playlist of all one’s songs that have the word “birthday” in the lyrics. PlayLyrix is priced at US$5.00 and requires Mac OS X 10.3.
