Comment (by blobfolio):

 I uploaded a handful of test files to a site and debugged the raw ID3
 data. Here is what that turned up:

 `MP3`, `FLAC`:
   None of these had anything like a file creation timestamp, only meta
 related to the recording like "year".

 `MPC`:
   ID3 error: `Format not supported, module "module.audio.mpc.php" was
 removed.`

 `MP4`:
   This is stored exactly like MP4 video:
 `$metadata['quicktime']['moov']['subatoms']['0']['creation_time_unix']`

 `WMA`:
   Works just like video "asf":
 `$metadata['asf']['file_properties_object']['creation_date_unix']`
