I have an ancient iPod Nano, one of the tall, thin ones with the click wheel; it’s got a whopping 2GB of storage!!!

Anyway, it plays music just fine. Except it won’t play one of my BBC Radio 1 Essential mixes-which are extremely long single tracks, usually right at 2 hours. This particular track plays fine on my iPhone, played without issue on my Android phone, and works just fine on my PC.

All my music is MP3, and ~320kbps when possible.

Is the issue the file is too large to process? Or something else?

I will attempt loading a different Essential Mix track to see what happens.

EDIT: Tried a different Essential Mix track and it worked. So there is something wrong with that specific file, apparently. :/
