I would like to suggest that you add Zhuyin at least on the 'lyrics' tab of the 'Get Info' for podcast mp3 files.
Zhuyin... sorry, I was talking about Bopomofo. The symbols used in Taiwan to help students pronounce characters.
ㄅㄆㄇㄈ
ㄉㄊㄋㄌ
ㄍㄎㄏ
ㄐㄑㄒ
ㄓㄔㄕㄖ
ㄗㄘㄙ
一ㄨㄩ
ㄚㄛㄜㄝ

I think it is better in representing the sounds than Pinyin. So we should probably have that included in case some people agree with me.
