Add search to find ASIN automatically

[projx]

Hi

I just came across your repo whilst trying to find a tool that can add metadata to Audiobooks, prior to this, I was going to role my own. But I noticed we have to manually find the ASIN ourself, which is difficult for large libraries.

I was wondeirng if you could use this class to add search functionality to the interface:
