I was only kidding about the nerves part, Peter;-)

--By the way, when I want to learn a song from a recording, I always convert it to an MP3 so I can play it from any point quickly and easily on my desktop--as bonus, for some reason, it is a lot easier to hear what is going on, for purposes of matching pitch and such, when it is played through my computer speakers--I've got my synthesizer keyboard plugged in to the computer as well, so it is easy to play along at the same volume, and it is nearly always perfectly in tune--
