1. A method, comprising: using a processor to precompute a first media content audio signature before a first web search, wherein the precomputation is based at least in part on an audio analysis of an audio portion of the video content, and wherein the first media content audio signature comprises a characteristic distinctive representation of the audio portion of the video content; determining an entropy level of the first media content audio signature; receiving a first web search result associated with the first web search; and finding a video clip that sounds like the video content associated with the first web search result based at least in part on a comparison of the first media content audio signature using a distance metric and a determination that the entropy level of the first media content audio signature is high.
