Cleanup Invalid MP3 Files

1. Install mp3check
   
   1. Probably already available in your distro. Example: sudo apt install mp3check
2. Scan a directory of MP3 files with: mp3check -e -r -B -R -3 "SOME_DIR"
   1. This only scans files and reports issues, it does not make any changes
   2. This is recursive. Remove the lowercase -r to not dive into subdirectories
   3. -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.
3. Fix files with command: mp3check --cut-junk-start --cut-junk-end -r -3 "SOME_DIR"
   1. This will write changes to the files stripping out the invalid chunks. The file modified time will be updated
