Hey there - I was actually able to grab your file and replicate the error here. I've passed the errors and your file onto our developers for review.
Can you open up the Developer Console in Chrome, go through the process of uploading a file, and send in a screenshot of any errors that are listed in the Console?
Can you tell me how are you encoding your MP3s?
Interesting - you're not the only one to report this issue. It's clearly a new and exciting bug for us to hunt down! Passing it onto our dev team for review!
Hey there - sorry for the delay in response. Is everything still grey for you?
Handling this one privately. Cleared out a bunch of stuck import earlier today.
