YOU SAID:
they said one day you'll leave this world behind, so live a life you will remember
INTO JAPANESE
彼らはいつかあなたがこの世界を後にするだろうと言ったので、あなたが覚えている人生を送ってください
BACK INTO ENGLISH
Live the life you remember, as they said that one day you will leave this world
INTO JAPANESE
いつかあなたはこの世界を去ると彼らが言ったように、あなたが覚えている人生を生きなさい
BACK INTO ENGLISH
Live the life you remember, as they said that one day you will leave this world
That didn't even make that much sense in English.
