Chrome Browser Extension for VKontakte

We need a Chrome browser extension that adds an icon to each song within the Music section of [login to view URL] Clicking the icon should download the following information: 1. All ID3 information for the song to a mongoDB instance. [ID3] 2. The direct download link for the song as a new data item to the DB record. [DirDL] 3. The actual audio file to a private folder on Google Drive. Then the link to this file must also be added to the DB record. [audioFile] There are browser extensions that allow download of the songs, but we need one that gives us all the information, the direct download link, the file and its private location where it is sent to the Google Drive. The extension needs to post a notification when tasks are completed and should warn about duplicates. This will NOT be a public extension. All rights for this solution will be retained by us.
