My wife has a bunch of cassettes with Christmas music on them. She lost one this year as it was dragging and I couldn't get it to quit. I need to transfer them all to a dedicated mp3 player that she can plug into the audio in port while the cassettes left still work. I transferred all my CDs to an ipod several years ago. Instead of changing CDs I just touch the screen to play what I want. Most of the time I just go to "all music" and choose "shuffle" and let it go through the 900 or so songs on it. The ipod is dead technology now and the smartphone has replaced it but I have it and am going to use it as long as it lasts. I have an old Pioneer sound system in my garage turned shop and I added a blutooth receiver to it where I can blutooth my smartphone which has Pandora, S/XM, and Amazon music on it plus I can connect the ipod without using a cord.
