Add some sort of progress indicator when uploading MP3s

When adding MP3s to Deezer, there is no way at all of seeing progress of the uploads or even if the upload is working. Refreshing to see the completed uploads seems to stop all uploads that were still in progress. It seems like this should be simple since every website on earth has a progress bar when you’re uploading something to it. And customers have been asking for this feature for over six years… Please add a progress bar or any indication at all that the files are being worked on.
