I actually use foo_winamp_spam to provide interface to my shell plugins - I use BB4Win (www.bb4win.org
- blackbox for windows), it has 2 good plugins (BBMuse - title display and multiamp - control panel) for Winamp. The latter supports Foobar2k, but only the earlier versions. It also has a plugin for FB2K controls and title display, but it's less developed and less stable (and also does not allow me to have both title and controls at once) - BBFoo. Using the winamp_spam, I am able to keep the interface consistent and usable.
