Be able to re-arrange songs, even while the song list is sorted.

I have a playlist with like 200 songs in them. If it's not sorted at all, (or I sort by the '#' column), I can change the song order around. But what often happens is I sort by artist or title, and then I want to set up a mini-playlist of 4-5 songs that I can play by turning 'shuffle' off. However, I can't do this, since I can't drag songs around.

So, simple suggestion: be able to move songs around, even in a sorted list. You don't have to change the order of the entire playlist; just allow the 'sorting' to be broken. If I want it back I can hit the column again.
