I mean, if they are smart, they will release a new single before her radio shows next month. "Sparks" has been getting decent rotation for about a month and a half on Houston's HAC station, that she's performing at on 9/20 (the day of the Emmy's 

). "Sparks" is done on basically every other station and she could use something fresh to get people interested in seeing her at the two shows (even though she's not performing alone).
The only thing is that this whole HAC movement needs to end now. If they release something else, it has to go to both formats. She will not see any success, or have a chance at it, if they continue this futile idea that she's an HAC artist. "Younger" doesn't return till about early/mid-September, she has the time to properly rehearse and shoot a video.
