There is currently no guideline on how to use work types in popular music. As discussed on mb-style, it is language dependent whether all works in popular music are 'song' or if some are 'song' and some are 'instrumental'. If all works are songs, then there is no point, and if there is no agreement on whether 'instrumental' constitutes a distinct type, it is best to move that information out of the ill-suited work type system.

In light of that, this is a proposal to clarify that works of popular music do not, in general, have work types, and that the proper work type for works of popular music is to set nothing.
