Automatically rename music files by music "thumbprint"

[valeriolucciola]

I am looking for an app that will scan mp3s and identify music files with blank or "unknown" labels.

A few years ago I had a froyo phone. I downloaded an app that would scan my mp3s and rename them based off of a database of music "thumbnails". Now that I'm back on android, I can't seem to find anything like that. It was a free app but I would pay for an app that properly renamed my files, updated tags, and added album art.

Any help would be greatly appreciated!

Thanks
