This is a little program created by Jason Freeman a . Basically it looks at your iTunes library and creates a short music file that represents who you are in terms of music.
His description of the app:
"People often ask me what music I listen to, and I find it difficult to describe my enormous music collection in just a few sentences. So I created iTunes Signature Maker (iTSM) to answer in sound a question I cannot answer in words. iTSM analyzes your music collection and creates a short audio signature to represent it.
iTSM selects a small number of your "favorite" tracks based on some simple selection criteria, such as the number of times you have played them or the rating you have assigned them. Then it analyzes the audio content of these files, combining a small bit of each of them to create the signature."
