Play around with SoundAround! SoundAround is a quick and easy way to preview large libraries of sounds. Just drop a folder of sounds (or a folder of folders...) and press the buttons to flip through the sounds. The "auto next" feature automatically flips through all the sounds.

This is for previewing AIFF, WAVE, and SD2 formats only. download the Mac OSX version here.
Source code for Max/MSP is included.
