Yes, you do have to listen for the differences, but they are relatively easy to hear. In passing by a room with one playing over the other, a person would never notice. However for myself, a person who sits down to listen to music i hate to be bothered by a heavy bass, or a sharp high end, so the differences matter.

It was great to listen to all those.
