It would be awesome if the lyrics provided by Genius (or some other third party like Musixmatch for example) would be visible in the touch bar.
I really like to read along with the lyrics of music when listening to it, but this isn't practical when I am using other applications on my MacBook. If Spotify would create a plugin for lyrics to be shown on the touch bar this problem would go away. It would create a really user friendly way for showing the lyrics, and there would finally be a perfect plugin for the touch bar.
It is probably a lot of work to develop this with good usability and its probably a lot of work to sync up all the lyrics but the users of Spotify could do this collectively like what Musicmatch used to do a couple of years back when they still worked together with Spotify.
