For music lovers on Mac that like to have lyrics with all their tracks, give Get Lyrical a shot. It is a small freeware that works in sync with iTunes, and grabs the lyrics for any track in iTunes library from the internet.
The software presents three options for choosing which songs to get the lyrics tag information for. Tag Selection allows you to grab lyrics for all the currently selected tracks. Tag Current tags the currently playing track, while Active Tagging monitors iTunes for all tracks that get played and updates them side by side.
Get Lyrical also provides the user with the option to browse and edit lyrics right from within the software.
It requires Mac OS X 10.5 or later to work, and iTunes 5 or above must be present.
