Heavy layering or multitracking; in the context of pop and rock music, this may refer to the addition of elements such as chorused vocals or backing strings.
Radio versions of songs pushed to be more "pop" through the use of loud drum beats or other instrumentation changes.
A recording overseen by a producer who "imposes" their own distinctive "sound" or techniques on a band or artist; Producers frequently accused of this kind of "overproduction" include Phil Spector[1][2] and Mutt Lange.[3]
All five of these meanings share the idea that a record producer or mastering engineer has made "unnecessary" additions or changes to a record in the production process and, in doing so, has decreased the quality or enjoyability of the music. There is little consensus among music critics or producers about when the use of an effect or production technique becomes excessive. For this reason, some producers consider the term unhelpful, confusing, and subjective.[4]
Current trends
The excessive use of dynamic range compression has been bemoaned by critics as part of the "loudness war". In August 2006, Bob Dylan criticized modern recording techniques, saying that modern records "have sound all over them" and that they sound like "static".[5] Those responding to Dylan's comments seemed to assume that he was referring to the trend of increasingly compressed music.[6][7]
