`lms.el' is a frontend for Squeezebox / Logitech Media Server. More information on what a "squeezebox controller" is at https://inigo.katxi.org/blog/2017/07/31/lms_el.html Quick instructions: customize some basic parameters `lms-url' and run it with `lms' or `lms-ui'. Then, you could read complete documentation after pressing 'h' key. You can also run 'emacsclient -e "(lms-float)"' to display an independent small frame.
