任何歌词很少甚至没有歌词的音乐都是最好的。

Any music with little to no lyrics is best.

没有歌词，这首歌的意蕴就是音乐本身了。

Lacking lyrics, the song's meaning is the music itself.

And we talked about this before--that classical music, probably eighty-five percent of it, does not involve a text, and that's a whole different ballgame because then you have to communicate meaning in a completely different sort of way.

我们之前也说过，古典音乐，大约百分之八十五，都没有歌词，所以这就让这两者产生了本质的区别,听众必须用完全不同的方法理解音乐的内涵。
