Is that a face lifted one. E.g.. mib3 or mib2.?.
On mib2 I play them from the file menu, you can play them from the tagged file data. There is also a limit on the number of files you can have in each directory. Since it isn't a PC or Mac it just doesn't see beyond that limit so won't play the files. Some people get over this by splitting the files into subdirectories so they don't go over the limit. I only use FLAC so unlike mp3 I keep in those limits so I don't have that issue. Might be
@Seriously? Who had that scheme. Someone did.
Hit the limit at 1,000 so if indexed you wont see anything above that. Then you have limits on the filename. See mib2 limits:

I seem to recall the mib3 limits are relaxed. Worth checking the manual if it's one of them. Mib2 is an old style program with list pointers and stuff. I wrote programs like that many moons ago. The array is a fixed declared length so you run out of puff which is the mib2 limits.

HI Just got a 2021
Cupra Ateca, C&S happy with it so far, bit different from my Scirocco R, certainly has a few more toys, one thing I can not seem to work out is
how to play music files, On the Scirocco I just put them on a sd, put them in the slot and it played easily, Is there a SD or USB...

That was more about album art. mib2 if you want it you can drop your own 500x500 call cover.jpg. One per folder. Observe folder limits for mib2. File name limits etc. The issue is when people drop all their mp3s into one directory or it trips on file name limits. Those limits above. Start small and test.
