Are Blackness and whiteness useful concepts in the study of popular music?

I do not believe these are useful concepts in the study of popular music, due to the fact popular music genres were created from different aspects of different races, such as Rock music. Also in cities such as London or New York, there are many different races and people of mixed background, that develop new music from a genre that already exists, they do this due to influences of music or culture from their location.

 For example, the music genre of ‘Reggaeton’, Reggaeton's predecessor originated in Panama as ‘reggae en español’. This started as Reggae music began to influence artists in Panama and Puerto Rico in the 1970s. As the Spanish-speaking musicians began to work with reggae, they began to modify it to include more traditional Latin American musical styles, The vocals are very similar to American hip hop, Reggaeton blends West-Indian music influences of reggae, dancehall, with those of Latin America, such as bomba & salsa. While it takes influences from hip hop and Jamaican dancehall, Reggaeton is not the Hispanic or Latino version of either of these genres; Reggaeton has its own specific beat and rhythm. This shows exactly how the concepts of whiteness and blackness can not work to study popular music, as Reggaeton has influences from ‘black music’ and is not performed by either white or black people.
