Poppagator, true there is no tapping in the Bushwhacker video, but if you do a little research you will find plenty of tunes written with some tapping involved...such as "Spin", tapping for me, is fairly mis-represented by 80s rock guitarists showing off, and if its done on an acoustic, then its quite easy to look like a wanna be electric guitarist.

My view is that, even if a piece has been written for a particular style or technique, why is that lesser music?

If you think about it, throughout time, music has been written this way, often orchestral works are based on a series of intervals that the composer was experimenting with, Beethovens 5th for example da da da daa, that minor 3rd interval, appears in the 1st, 2nd,finale and coda of the entire symphony..... great pieces of serialism from Wagner were written purely because he'd experimented with different scales, Jimi Hendrix wrote Machine Gun, because he wanted to use the sound of the guitar to represent machine gun fire....etc etc..throughout history people have based compositions on new scales, interpretations on intervals, sound effects..what makes guitar tapping any different?
