Music licensing: the most common Christmas Eve surprise
Most churches already hold a CCLI Church Copyright License, but that license alone does not cover streaming. According to CCLI, its Streaming License extends that coverage to online worship for songs performed live by your church's musicians.
The catch is recorded music. CCLI says the standard Streaming License does not cover master recordings such as artist tracks, backing tracks and multitracks; those need its Streaming Plus license, which CCLI describes as covering audio only. If your Christmas Eve plan includes a soloist singing over a track, or a video with a soundtrack, check this first. Christian Copyright Solutions offers a separate streaming license, WORSHIPcast, which its published summary says also does not cover pre-recorded music.
Old carols are not automatically safe either. Many carol melodies and lyrics are centuries old and in the public domain, but a modern arrangement can carry its own copyright, and a recording always has a separate copyright from the song itself.
Even with every license in place, a platform can still react. YouTube's help center says a live stream can be interrupted even if you have licensed the third-party content, and that it may first replace the stream with a placeholder image. Live musicians playing in the room are far less likely to trigger this than a recording played through the sound system. If a track is essential, consider whether that segment needs to be on the stream at all.
