Moderators don't like such plugins (as violating SDK, though this plugin doesn't use any dirty subclassing, just legal callbacks) here, so I decided not to publish it.
Window procedure hooks are evil, message_filter is OK.
...it’s possible (and very easy), but I won’t do it. For playback it would be just useless annoying animation in taskbar.It’d be useful for converter, I wanted to do this, but Peter said there’s no any converter callbacks...
it even replaces the window thumbnail in alt-tab with the current album's cover art
