Yah, the music obviously has changes-- otherwise it wouldn't entrain and train your brain.
Oh, believe me, if you use iMusic while working, studying, whatever, your stamina will go through the roof, and you will have an easier time memorizing things.
I guess if you aren't doing intensive mental work for long stretches, you won't notice these benefits.
Believe me, you use iMusic in demanding situations and it will work for you.
I have got so many people using this around me now, it is an across the board solution. I truly believe that anyone who says it doesn't work for them, is letting themselves down by not using iMusic to its potential.
