Did you find the answer? To be honest I am tired to look for so many solutions for so many software I have where things keep changing so much that I might as well be a fulltime forum digger / tweaker, just to keep things working for me. :-(
I didn't find the plugin and didn't dig in that huge thread mentioned. So, I'd be curious how you solve this. For me, it's to get mixcloud pages and others to see and play inside Musicbee.
