Cleanup Invalid MP3 Files

Install mp3check
Probably already available in your distro. Example: 
sudo apt install mp3check
Scan a directory of MP3 files with: 
mp3check -erBR3 "SOME_DIR"
This only scans files and reports issues, it does not make any changes
This is recursive. Remove the lowercase 
-r to not dive into subdirectories
-B causes it to allow variable bitrate files. If your player doesn't support VBR, remove this flag to identify files that are VBR. Note: mp3check cannot convert VBR to CBR, you need tore-encode for that.
Fix files with command: 
mp3check -r3 --cut-junk-start --cut-junk-end "SOME_DIR"
This will write changes to the files stripping out the invalid chunks. The file modified time will be updated
Notes:
The recursive option does not appear to work properly and only seems to go 1 directory deep
The Dirname handling seems unusual. You may need to use a /* at the end for it to scan the entire dir
