Mike .....they know what they are doing marketing wise for sure. ......lets face it Arrangers = Home players period and thousands of them worldwide......the live gigging arranger musician is a minuscule percentage if that in that market versus pros who are using so many other methods to gig live & record with out using an arrangers at all. Money drives the different markets.....lumping them all in one cuts PROFITS just like Light Beer & Regular Beer with choices more people BUY different things! What I would assume that in the future music stores will be a thing of the past pushed out by ONLINE stores....... clueless salesperson, poorly stocked stores, overpricing versus the Internet all combine to be the demise of Music stores as we used to know them.
Sad facts but that's life.
