I love Roon’s moving lyrics but they are only available on certain tracks. Can us users get involved in creating moving lyrics for those tracks that don’t have them?
It is a service that Roon licenses. The company in turn gets licenses for the distribution of lyrics.
So my guess is no user involvement.
The Lyrics tag can have user-supplied lyrics, and Roon could display said contents if the other services came up short. That’s my best idea.
