How can I upload multiple tracks at once / can I upload more than one song at a time / How can I upload a bunch of songs at once?

At the moment the only way to upload multiple tracks at once is to create several browser tabs of eMastered.com, and upload a different song into each browser tab instance of the site.

This is a feature we are exploring adding in the future, but as of now this is the best way to upload multiple tracks at once.
