Great point.
Fun is usually what initially gets us into this hobby.
Those early years of discovery were certainly exciting for me. It was only much later that a certain amount of world weary cynicism began to creep in.
At the start of it all, it felt like being a kid in a giant toy shop.
I think the OP was questioning the validity of online listening tests via YouTube but that's not the main point of it anyway.
As we always like to say, there's no real substitute for listening in person - YouTube is for fun.
Everyone happy now?
