First would there be a way to have it countdown how long until the current track is submited to audioscrobbler?
And second how do I display the file size in megabytes instead of bytes?

For the second question, this is what I use:

thank you very much!

For the first question: Indicate Audioscrobbler submission

I'm already using that to indicate for submissions what I would like to have is a timer counting down to the point in the song when it will be submitted.
