TagLib Audio Attributes
That's a great looking icon, and I'm happy to use it. But were there supposed to be other icons? You say iconset but I'm only seeing one.
*.icns is a set. It contains multiple icons.
It's still not perfect, but if you want me to help to deliver the best results (also for Retina), let me know.
Ah, gotcha. The icon is great! I put it in the latest OSX build. I'm very happy with it, but if you'd like me to update it just send me a new one.
