I can get all of the files under a single folder, but not all files under all folders. Due to the fact that I'm separating each song into separate folders by title in order to reduce file name conflicts, there isn't a way for me to grab every file recursively. 

Google Drive uses milliseconds for the last modified timestamp. If any timestamps need to be updated, I gather them all up and commit them all to the hashcodes file at the end with a single upload.

I've made the change to add the "Check for updated files in cloud folders" settings, and I completed a second sync in 30 seconds if I disable the option. So you may choose to use this if you know you haven't updated any of the files on the cloud.
