Symfonium fails to properly render these Karaoke-style lyrics (with word-level timestamps), whereas most Chinese music players handle them without issue.
Furthermore, I am facing a format conflict regarding translations: ESLyric requires translation lines to have identical timestamps to the original lyrics, but Symfonium does not handle this ‘double timestamp’ format well (preferring translations without timestamps or merged lines). However, removing the timestamps breaks compatibility with ESLyric. This lack of a unified standard is very frustrating.
