It appears that iTunes uses a non-standard tag to identify MP3s that were downloaded as podcast and thereby organize them differently in the iTunes display. I am wondering if Jaikoz would allow me to add this tag to MP3s that do not already have it? If not, is there another tool that would do this?
Support for iTunes PCST tag?
Jaikoz does not allow to create the PCST frame at the moment, but you can add arbitary WXXX or TXXX frames though.
