Some people use a Sony MD recorder but how they transfer the songs to their computer I don't know.
I did it a really complicated hard way...I recorded the shows on one of those handheld recorders like people use for school to tape lectures or whatnot and then I recorded each song individually onto my computer using a mic. Had to have total silence while I was doing it which was hard since there are a lot of people in my family, most of them loud.
Good luck with your recording endeavors
