@Vivek - From dashboard if you click on 'sugegst song' on left side links, you should get only open requests... If you click on "view all" ... you'll get all requests however open requests get the priority in sorting and all open requests are highlighted with different background color...

Are you saying we should move all closed requests to archive even from "view all" section ????

No. My suggestion is Instead of "View All" we can convert that to "Archive" and show only closed requests there.
As anyways LHS link shows Open requests.
Thanks for pointing I did observe the color coding and priority
