The only problem is label's position and space. I have implemented progress bar for the the player which took some of the available space. It will get merged in some time.
How about editing the application title instead of adding a label?

Thanks for your feedback. Yes that would be a good idea but generally the file name is shown in the media bar There is some white space above the bar. So if we could increase the height of midi bar and then include the current song being played and occupy some space. If not possible then we could edit the title :)

Yeah space from the menu can be taken. Ultimately it would depend upon your implementation. If it looks great and tidy then there wont be any need to edit title.
