The new one is just a web UI with options for streaming music. There were talks of the old original Winamp going open source though, which bought nostalgic memories to many. Eithercase, with so many music players on both Windows and Linux, I doubt Winamp would a niche case to fill.
I have the old one (5.x) installed and use it regularly. Is it still available for download anywhere? Would love for that one to be officially open sourced.
