When I´m searching for Winamp in this Forum, there are 2 (!) unreplied threads. 
I would love to see something to control Winamp over Home Assistant like the usual controls play, pause, next, etc., but also the abilty to select playlists. (Maybe with a third party tool installed in Windows)
I´m using this excellent remote control for android, which can do almost anything. Maybe it´s possible to integrate it in Hassio?
