Control Center/Virtual Desktops

I live and die with the virtual desktops, and have a problem with making apps 'stick' through all the desktops. Control Center and Tab Launchpad work fine, easy to configure this, but the one I want doesn't work, and that is Winamp.
I really want it to be on each desktop, but when I try to configure it, there seems no way to lock it in as just winamp.
When no songs are playing, it follows the desktops because it is called Winamp, but when I play a song, the title changes to Winamp + (song title) and doesn't lock into each destktop. I tried the 'class' setting, and matching partial names, but no go.
Anyone do this successfully, or is Control Center buggy like a lot of the utilities?
Here is the goofy part: With a playlist loaded, when I choose "match partial names" it works, but as soon as I load a different playlist, it stops following the active desktop.
Gotta have it, anyone know how to get it?

Thanks,
John
