I've streamed Sunny quite a bit in the past, and I am 100% positive they aren't playing as many currents. Heck, I can LOOK and see they aren't. Just look at Mediabase on AllAccess. This month (or late last), they quit playing these completely:
Lady Antebellum - Just A Kiss
OneRepublic - Good Life
Adele - Set Fire To The Rain
Kelly Clarkson - Mr. Know It All
Colbie Caillat - Brighter Than The Sun
P!nk - Perfect
Lady Gaga - The Edge Of Glory
...and added no new songs. Last I checked, the songs above were near the top of the AC chart. The ONLY AC current they're playing now is Adele's "Someone Like You." If you look, they dropped quite a bit of recurrents as well. Yes, they were playing 7-8 currents at once last month and typically did in recent times. They are playing some re-currents like Gaga, Black Eyed Peas, Cee-Lo Green, etc. that they might not have in the past. Still, it's much less current-heavy.
