Why the iPod Classic remains one of the best ways to listen to digital music

Love my 120GB iPod Classic. My old Plug-in Prius had a little tray in the console for it, and the USB port was inside the console too, making it all tidy. My brand new Prius Prime, however, still has the tray, but now the USB port is outside… untidy. But I’ll live. Apparently everyone uses their phone which they need access to, to play music.
I am considering dropping $50 to replace the battery in the iPod…
