Apropo of nothing, for all of Spotify's UX changes, I feel like skins and visualization of the music are missing from their desktop/web client. For desktop they've taken away the full-window playlist view in favor of a sidebar-only playlist. That's one thing I miss about being able to use Winamp or Windows Media Player to play music on a desktop :'(
How is it that the Winamp 2.x visualizations from like 1999 are more badass than any music player I can think of today? I had no idea Webamp existed until today and now I'm thinking through how to make it my full-time music player.
Personally I liked very much the more standard car-DIN-form factor visual plugins. They could also be stacked with separate equalizer or playlist controls.
