Another thing is free. Music you know well. I had Fleetwood Mac’s “Sometimes”, off of Future Games, in my my head and I started to look for it in my CDs It would have taken forever..my filing system sucks…So, since I had the song inside my head already, I sat down and listened to the whole thing from from start to finish. I might have mixed things up a bit, but it was very satisfying….Great fidelity and stereo separation… It was what ever I wanted it to be. I added a horn section for while, my choice,,,Which is cool, because if I ever go deaf, I’ll still be able to listen to music…is that cool or what?
