I would like to purchase either a Sony CDP-CX355 or CX455 magachanger for my familiy's CDs and I was wondering how easy it would be for my family members to find a CD. Can you search by artist name within a group or can you only search by album name? If someone could break down the steps to finding a CD I would appreciate it. I don't want to purchase something that they will need help finding their Cds all the time. THANKS.
