Well I for one think Electronic Music has too many sub-genres. Like if you change the timing of the highhat or the type of synth you're using it catapults you into a different genre. Whats that all about? Why does it need to be so segmented?
So that when I look at a party in my area I can know if its a party where artists will be playing progressive psytrance or forest psytrance. Because they're different.
Is this so hard to understand for you?
