It will probably continue to grow at radio for a few more weeks until the holiday freeze comes in. Depending on how much life it has after the freeze is over, it could gain a bit more.
For those unaware, the "freeze" is referred to a period in mid-December through early January where many radio stations will "freeze" their current playlists in exchange for Christmas/holiday songs and year-end countdowns. This tends to affect current songs by hindering their updates (either very small audience increases or large audience decreases). Most of the time (once the freeze is over), the song's audience tends to regain back to normal and gains a bit more. I recall this happening with Firework and TOTGA.
It will take time to grow like JGMAR.
