The advent of the world wide web (and Zach Braff's shameless need to promote his own musical taste through soundtracks) has created exponential growth in available information around otherwise unknown, obscure musical band talents as well as access to existing uber-bands via downloads, websites, tours, email newletters, etc. With this industry explosion has come the creation of various web-based musican/song/album customized search and listening services; think Yahoo!Launchcast and Pandora.
The newest iteration of this trend aims to introduce you back to your own collection of music (which, if you're anything like me, has probably exploded with tantamount zeal) rather than bombard you with more unfulfilling, consumption-driven musical suggestions that you will never, never, stay on top of. Instead, Soundflavor, downloads onto your desktop and creates a vertiable personalized DJ using your own iTunes assortment. Though this tool is still in its infancy and is likely to change several times during its development, Soundflavor is nonetheless a very cool invention and well worth a look.
