To keep my answer short for now.
I was drawn to its abstract nature and the deep level you can listen to it if you want to.
Also as a dj theres nothing like it if you want to dj like a musician rather than just playing tracks.

Also the freedom it alows you as a producer you can be an arty c*nt with it if you are that way inclined.
And of course you can rock a party with it if you prefere it that way.
