If the landlord missed it, you can find other songs you heard at that time and savor them.
If the landlord really likes that kind of song, there are many online.
In short, it doesn't matter if you find a better one, and it doesn't matter if you can't find it. Just listen to other songs. You may not find it now, but you may find it sometime in the future.
At that time, I looked for the game I played as a child, but I couldn't find it many times, and then I came across it by chance.
I hope the landlord is lucky. . .
