A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions (Jim Samson on March 4, 2012, in Grove Music Online). It is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably (Wong, 2011). Music can be divided into different genres in many different ways. The artistic nature of music means that these classifications are often subjective and controversial, and some genres may overlap. There are even varying academic definitions of the term genre itself (Wikipedia).
