Fix for podcast file missing some metadata

This file wouldn't play by default (on my M2 Pro Mac Mini) because of what appears to be missing/corrupt metadata, this file should have everything needed

Old:
```
"FileExtension":"flac",
"Format":"FLAC",
"FileSize":"351705020",
"OverallBitRate_Mode":"VBR",
"StreamSize":"0",
"File_Modified_Date":"2024-01-11 20:07:08 UTC",
"File_Modified_Date_Local":"2024-01-11 12:07:08",
"Encoded_Application":"Lavf58.29.100"},{"@type":"Audio","Format":"FLAC",
"BitRate_Mode":"VBR",
"Channels":"2",

"extra":{"MD5_Unencoded":"00000000000000000000000000000000"}}]}
```
