| The state which a song is in when it has been played and assembled entirely within the confines of a small room designed precisely for the purposes of eliminating every natural noise from the vicinity with the exception of the musical instruments, which no longer sound quite natural, either.
The term is still applicable to a song which has had several different recordings of a particular instrument, such as guitar or voice, layered one over another to make it sound like the song has that many more instruments. |
