I have not seen any reference in this forum to the excellent Kodi Plugin for Squeezebox by Marcelveldt published and discussed in the Kodi Forum, thus a quick post to make the community aware:

Together with other Kodi plugins (Lyrics and Artist Slideshow) this allows very nice visualizations of Lyrics and Artist pictures while having all advantages of the Squeezebox Infrastructure. I use this plugin on a raspberry pi OSMC installation connected to a TV and AV-Receiver and it works very well (some bug fixes and options are discussed in the thread).
