You may have already added lyrics to your songs by using an MP3 tagging tool or a software media player that has a built-in metadata editor (like iTunes). However, this method is only good enough for displaying all the lyrics in one go. If you would rather see the words displayed on-screen in karaoke-style, then you'll need to use separate files that are in the LRC format.
This is a special format that not only contains the lyrics for a song, but also has timing information in order to correctly synchronize the words to the playing music / singing. Files ending in .LRC normally have to be the same name as your song and are actually just made up of simple lines of alphanumerical information. Using LRC files isn't just limited to jukebox software either -- most portables these days such as the iPod, iPhone, iPad, and other MP3 players and PMPs support the LRC format so you can sing along in Karaoke-style while on the move.
You can create or download LRC files for songs, but a more practical way is to use a plugin for your software media player such as the free MiniLyrics application which does this automatically.
For more information, read our LRC format definition article which goes into far more detail.
