Xenoblade chronicles 2 .NOP files

[MarsLink]

Hello,

I extracted the ROMFS of my game and found .nop files.
I can listen to their content with foobar, but is there any way to find the original music title?
Is it stored in the file or should i find the names on internet ?

The .nop haven't the name inside, i think it's better to examine bdat files
