I've been re-writing all of the media renderers and decided that the default browser audio player was ugly. Figured I'd fancy it up a bit, and am probably also going to skin the video player as well.
This is the audio player. The thumbnail is the custom_thumbnail added when creating a post to a .mp3 file.
Still playing around with the layout, and will probably add a few more controls (playback speed, prev/next and support for multiple tracks, etc). The background image also animates during playback.
I believe it should be easy to provide a user option to prefer the default browser player, so I'll probably add that too.
