Yesterday, the Winamp source code, build tools, and associated libraries for the Windows app were published on GitHub, allowing anyone to provide bug fixes and new features to the iconic media player.
However, its license prohibits the distribution of modified software created through the release of this source code.

Yeah same here, since forever. Other players are a lot more flashy and appealing to the eye but I haven't found any that make manual library management etc. as easy as foobar2000 does, and Columns UI makes it look modern enough for me. Only on Windows though, the macOS and Android ports are pretty rough...
