Snow Leopard to Provide Icon-Level Previews

AppleInsider reports that the preview version of Snow Leopard provides users with a quick way to review audio files within Finder:

One person familiar with the pre-release software notes that hovering the mouse pointer over an audio file in Snow Leopard's Finder will trigger a triangular 'play' button to appear on the icon itself. Clicking the button will allow the audio file to play within the Finder, but without opening a specialized preview window.
