Methods and a computer-readable storage device for detecting shared audio content between first audio content information and second audio content information is provided. The methods cluster similar fingerprints to lessen the impact that similar or repetitive sounds have on the final decision, thereby producing a more accurate final decision about whether the first audio content information shares audio content with the second audio content information.
