labels are communication - without them how do you describe?

rigid categories defy the purpose of music and for listening they are superfluous.

For telling other people they are the way we tell it and are as personal as the teller. But ya gotta start somewhere.

And as for archiving - how do you pigeon hole? No pigeon holes - no archive - just a pile. With the aid of computors the cross referencing and multiple entry helps but once it gets too comprehensive it is just a dilute mass. So fairly tight categorisation usually wins, because the human mind is not good at data - better at information and superb at pattern recognition.
