Like Pronouns do we have to many music genres?

I enjoy making things as complicated as possible. Slice & dice. Thinner, please!

I've always thought a lot of genre-classifying is silly.  I like what Phil Lesh said - "The Grateful Dead is its own genre".... But I'm mostly a post-punk guy... 

And I do not agree about there being 'too many pronouns'. 

Is Adele a pronoun for a genre too difficult to describe in polite company?

doesn't matter as long as it's obscure

I don't see an issue with different genres to describe various types of music. Pronouns are pronouns. Nobody needs to reinvent the wheel, especially if the new version won't roll.
