CDDB does not have such global identifiers CDDB没有这样的全局标识符。
I made the choice not to use the CDDB (Gracenote) disc database, even though it is very comprehensive 虽然CDDB (Gracenote)磁盘库非常全面，但我还是没有选择使用它。
This is important, as demonstrated by recent cases where CDDB data was tainted by gag entries using foul language 这很重要，可以由最近的例子证明：CDDB数据曾被使用污秽语言的恶作剧所破坏。
