it looks like this:

also you can resize it like this too:

if you want it you can grab the .nib file here
to install go applications/play.app ctrl-click and select "show package contents" then /contents/resources/english.lproj copy the original "AudioLibrary.nib" to your Documents or another safe place for backing it up. and then drag and drop the other AudioLibrary.nib, start play.
i can't know what will happen it may crash or do something bad but it works fine with me, just backup the original file.
