In olden days, artists (and their labels) were thrilled if they could get ANY play on the radio. Now their labels get their undies in a bundle about the i'Net. We need a better definition of fair use for the casual user.
They are also making a big mistake

in wasting money on the lawyers to prevent the distribution of a lousy quality copy and WAKE UP to the commercial possibilities of the web, video, CD/DvD photo albums, etc. If usage/exposure is what they want, and payment is what they crave, make it EASY and AFFORDABLE to purchase licenses for those purposes. How many copies of Sally and John's wedding DvD are going to be resold to illegally distribute the latest Nashville sob song outside the label's control? But Sally and John would love to have the original instead of a knock-off as long as they can still afford it. And THAT is brand loyalty the label's artist can't imagine the value.
"Dear? Remember OUR song? Well, for our anniversary, I bought us artist circle tickets to their concert tonight!"
PRICELESS? Well, let's see...
The artists, the venue, the manager...heck, even the janitor gets paid. And the husband gets...OK, let's keep it G.
Do you know, some couples don't even remember what "their song" was!
