ILSP researchers have developed methods for calculating the similarity between songs based only on the audio content.

The method relies on combining similarities of three main aspects of music, i.e. rhythm, timbre (or alternatively instrumentation) and harmony.

The method is evaluated in MIREX 2013 Audio Similarity Task with encouraging results. More details about the method can be found in:
