iPod Classics are the bomb and Apple should bring them back as is with a SSD and servicable battery – the way mine is now. I love having 100+GB of offline music, for airplanes, travel, etc. No stutter, no buffering. No wireless drops over bluetooth.
I still have an iPod Classic. I drive through remotes area without signal, so suggestions like Apple Music, Spotify, Pandora, etc., aren't all that helpful. I'll continue to use Sirius/XM since I got a great deal on that. Also, I have music that's not available for sale.I have been very seriously considering getting an MP3 player to leave connected in my car.
