Some file do not play in playlist

I have a playlist. One file gets loaded “Spirits.mp3” and another does not “Stressed Out”. Files are on a NAS, locally mounted and accessible, permissions are fine, yet I cannot for the life of me understand why certain files do not load.

This is my playlist file: temp.m3u

#EXTM3U
#EXTINF:202,Twenty One Pilots - Stressed Out
NAS/music/mp3/Twenty One Pilots/Blurryface/02 Stressed Out.mp3
#EXTINF:203,The Strumbellas - Spirits
NAS/music/mp3/The Strumbellas/Hope/01 Spirits.mp3

Files are both accessible:

root@volumio:/var/lib/mpd/playlists# file "/mnt/NAS/music/mp3/Twenty One Pilots/Blurryface/02 Stressed Out.mp3" /mnt/NAS/music/mp3/Twenty One Pilots/Blurryface/02 Stressed Out.mp3: Audio file with ID3 version 2.3.0, contains: MPEG ADTS, layer III, v1, 128 kbps, 44.1 kHz, JntStereo

root@volumio:/var/lib/mpd/playlists# file "/mnt/NAS/music/mp3/The Strumbellas/Hope/01 Spirits.mp3" /mnt/NAS/music/mp3/The Strumbellas/Hope/01 Spirits.mp3: Audio file with ID3 version 2.3.0, contains: MPEG ADTS, layer III, v1, 320 kbps, 44.1 kHz, Stereo

I’ve noticed this with other mp3 files as well. VLC reports both files as:

MPEG Audio layer 1/2 (mpga), Stereo, 44100 Hz.

Any thoughts on how to debug this further?
