Hello ​@mrdrprofessor, welcome to the Sonos Community!

I’ve marked this thread as a feature request and forwarded it to the appropriate teams for consideration.

Thank you for the post!

The old mobile app theoretically included lyric support, though I never saw a music service that implemented it.

This ability has been removed from the newer version of SMAPI that v80 mobile app switched to.

Lyrics would be nice for every service willing to provide them.

For now I fire up the TV and use the Amazon app to my Arc, be more convenient and use a lot less power if the Sonos Controller showed them.

I must not be visual when I listen to music. I don’t need to look at the album cover, or lyrics. But that doesn’t mean others shouldn’t. This would be a nice feature for many. I’m happy ​@Sotiris C. has passed it on. 

Do you recall if the feature allowed for highlighting the specific lyric played currently?

As I said, I never saw a music service implementing it, but it doesn’t look like it.

You can see screenshots in the old API documentation here: http://web.archive.org/web/20230207111121/https://developer.sonos.com/build/content-service-add-features/add-lyrics/

Thanks.  The screenshot shows timestamps, which likely means that it did not highlight the lyrics.  Although it seems like it wouldn’t be too difficult to highlight lyrics given that info.
