Yes, but only if theres text there already. Still brings up the menu if theres no genre filled, which is most of the cases where youd want to change that field. (And yes, I know I can type ahead in the menu, its still cognitively less efficient than a type ahead text field).

You're in the "playlist" view.
I never use any other views
