For long, I wished Winamp would be open sourced. I don't understand the benefit of keeping it closed. I'm not sure I would be back to using it though. I'm used to my current player, which already does everything I would expect from Winamp, with a (arguably) worse look but much better UX. Audacious with the Winamp classic interface is also a great Winamp for those who (still) fancy this look and feel.
As you've clearly got something that fits your needs as do I by slowly making my own Winamp compatible player to run my old Winamp plug-ins (which were always closed source nor am I for or against OSS but it needs to be the dev that decides not external pressure) because I don't trust nor like what's happened with those that now own the brand.
Also source code is pointless without dev(s) & unless we're looking for AI to do all of the coding, whether the code is open or closed, the fleshy meat bag bashing the keyboard is still needed for the time being :)
Use what makes you happy & I'll keep making & using what makes me happy too :)
