That means that it doesn't matter how rich your language is it's just impossible to express music with words

Anyway, the conctruction main word + бы ни is a Russian analog of English main word + ever (like whatever, whenever)

Examples:

Что бы ты ни делал, главное делай это правильно. - Whatever you do, do it right
Где бы он ни был, я его найду - Wherever he is I'll find him

The same goes to the topic example but it was just too confusing to describe that with however. I think you know why. But the logic is still there.

I hope it helps
