Harmony allows you to import song lyrics and data from the SongSelect service, operated by CCLI. The SongSelect service has lyrics for over 90,000 worship songs. A membership to SongSelect and a Church Copyright License for your church/organization is required before you can use this service. More information on CCLI and SongSelect can be found on their website http://www.ccli.com.
Once you have your SongSelect account set up by CCLI, you can use the import feature.
You can import SongSelect .usr files downloaded in a web browser or on another computer by dragging them to the Harmony icon in the Dock.
