Looking at iTunes today, I've come to a conclusion that the fonts are really nice.
I have English, Chinese, Japanese and Korean songs and they do look really good together. Just wondering if it's one font or many fonts used? And of course what font is it?
EDIT: A possible match would be Segoe UI for English and Meiryo UI for Japanese. That's all I can find for now.
