I really doubt Still Into You is peaking. There are so many songs in the Top 20 that are going to get taken out of rotation soon (Blurred Lines, Clarity, Love Somebody, I Need Your Love, Radioactive, We Can't Stop, Cups, Treasure, Take Back The Payola, The Other Side, Get Lucky.)
Honestly, it looks like any song in the Top 25, maybe even Top 30 that isn't plummeting very much stands a good chance of getting into the Top 10 (this includes GGG), although obviously a few of them might peak within Top 10's reach like The Way did.
