On this week's Adult Contemporary chart (to be officially announced tomorrow, Thursday, along with the rest of the week's charts), "Ghosttown" holds at #20 from last week (it fell from #18 the week before). The song had 227 spins at AC with 2.656 million audience.
Elsewhere, "Ghosttown" is #2 on the Adult Top 40 'New and Active' list (kind of a bubbling-under tally). This is not an official chart appearance on the Adult Top 40 chart, it just shows that the song is actively gaining at the Adult Top 40 radio format. If "Ghosttown" keeps gaining, it could debut on this chart as well.
