Music content characteristic identification and matching

The present invention relates to a system and method to allow music matching for delivering music to users of computing devices connected to a network. A system and methods for matching media entities to associate closely related media entities are provided. In connection with a system that convergently merges perceptual and digital signal processing analysis of media entities for purposes of classifying the media entities, various means are provided match media entities using aggregation and non-aggregation matching. In an illustrative implementation, various factors representative of inherent characteristics of the media entities are employed and processed to generate data sets having closely related and/or similarly situated media entities. Once a media matching is performed on a library of media entities, the results of the media match may be persisted for the user from experience to experience.
