it appears to be just an added optional feature, a winamp-branded deezer subscription and client, with the traditional local play and customization and what-not still part of the 'free' program (presumably.. details are scarce).
but.. i left winamp years ago. i won't go back. i have playlists sorted and can just use vlc these days. idc about customizing or visualizations and that shit. i just want a player to sit in the background and do its thing. there's dozens of acceptable programs without a subscription sales pitch built in.
