This is a pretty important subject so I`ll add my two cents for what it`s worth.
I`m all for diversity in music. They don`t call it the universal language for nothing.
That being said........
GT is a private for profit company. Their 2 most important responsibilities are :
1) Give their customers what they want.
2) Make a profit.
If they don`t achieve those two things then nothing else matters because they go out of business. If there`s a certain genre or type of music or specific artist(s) that we want, then it`s up to us to request those . GT cannot be in the business of being the arbiter of what types of music we should be exposed to. Purchasing song rights cost money ( as we found out recently with the loss of a number of song lessons here) and GT needs to spend their money wisely if they`re going to stay in business. We , the subscribers have the power to determine what song content exists on GT. Therefore, it`s up to us to make it known to GT what WE want. That`s how the free market works.
Anyway, that`s it. Back to practicing guitar !
