Fourthed! That is, for the "display currently playing track name via growl" suggestion. Right now the only way to see the track name is to change tracks (or of course to switch to cog, but the point of growl is you don't need to do such a thing). If there were a hotkey to display a growl notification, OR if the play/pause hotkey would do it, this would be great.
Also, I'd love if the album could be displayed also, rather than just the title and artist.
(I'd be happy to try to do these things myself, and I've been prowling about trying to figure out how, but i'm not sure I'm clever enough. Could someone maybe give me a hint as to where to start?)
