Spotiamp features a builtin Shoutcast® server, so you can easily stream the music to any device supporting Shoutcast, such as Sonos.
I've installed version 5.8
I used the installed ver, but it shouldn't matter if you want to use the stand-alone ver. When it prompts you to allow network access, select public and private networks so the windows firewall doesn't block your server port.

To get the Shoutcast servers's codec to work properly in Windows 10, you need to enable the codec in the registry.
- Open a cmd.exe window as Administrator
- Run the following 2 commands
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\drivers.desc" /v "%SYSTEMROOT%\SysWOW64\l3codecp.acm" /t REG_SZ /d "Fraunhofer IIS MPEG Audio Layer-3 Codec (professional)" /f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Drivers32" /v "msacm.l3acm" /t REG_SZ /d "%SYSTEMROOT%\SysWOW64\l3codecp.acm" /f
Now you can stream your spotify playlists via shoutcast. Just enable the Shoutcast server in the settings menu and press play in Spotiamp.
Open winamp and go to File->Open URL. The URL to play is: http://127.0.0.1:5010/play.pls. Replace 127.0.0.1 with the IP of your computer.
this still works, and in the latest version of winamp (which the instructions' old link redirects to). I dunno if the reg keys are required but I think you can do that step before installing spotiamp, or at least probably before you run spotiamp. be sure to download and install winamp 5.9 or whatever old version you wanna try, then download and install the linked spotiamp, RUN spotiamp and log into your spotify account (mine is premium), then click the menu icon at top left of spotiamp and click settings > enable shoutcast server - and this is the point I believe you get the firewall prompt (I checked all the options). next you need to press the eject button in spotiamp to see your list of playlists, pick one, start playing, then go back to winamp (both spotiamp and winamp have to be running) and click the menu icon at top left then play > URL, and enter either the loopback address in the instructions or your relevant computer IP and click Open. I think I had to make sure spotiamp was playing before I could control play and pause via winamp. and of course, menu > visualization > start/stop plugin, and enjoy the milkdrop. Also I did this all on windows 11.
