There are 2 problems
When i am listening a song, for example, named "alone", i am adding some new songs into my playlists. Then the weird thing happened... the titles all of songs i add become "alone".
The other one is when i select the language as traditional Chinese, all titles in Chinese of songs are correctly displayed except in MY playlist viewed IN LIBRARY; that is, i view the same playlist in playlist windows is normally being displayed in chinese but in library it is shown in Korean.
hope my statement is clearly enough
