Ok, got a good example here.
Let's say you go to a Rolling Stones concert, the music is what you expected it to be, great,you are 100 feet from the stage (as usual at big concerts) and can't see details.
Suddenly somebody tells you that it is one of that amazing cover bands that sound and look alike.
Is it the same experience ?
No because you want to be in the same room with the guys that made rock history, you want to feel that vibe in the air, want to be part of that history, you want to think "hey those I'm seeing are the same guys that made rock revolution" music is important but any good cover band can play easy RS songs, may be even better tech wise,and without being drunk or stoned ...but it will never be the same.
