My thoughts on wedding DJ popularity:
Some audiences want to hear the songs 'exactly' as they remembered it on the original hit record/CD. No matter how much arranger keyboard work goes into emulating the original, we will "never sound exactly" as the original record did anyway (thank goodness!).
I don't like to be negative but the fact is, musical taste and appreciation (in the general population) has dropped dramatically over the years (no support for music programs in the schools, etc). A lot of the public take music for granted, thinking it's like turning on a radio. Easy on, easy off, turn it up, turn it down. I've spent years developing my craft and pour out all my "heart and soul" musically so if all they want is to hear the music exactly like the record,let them go with the DJ or turn on the radio (cheapest way to go). I think this is why most of my gig venues are geared to an older(over 40)audience because they grew up in an age before MTV.
Thanks for letting me vent, I feel much better now.Time to head off for my "appreciative" senior retirement community gig now and get home early too

Make music and be happy,

Scott
