Originally I thought they should have released it to AC and Hot AC stations the same time they released it to Pop stations, but now I would say after New Year's, maybe around January 3 or so. I don't recall Behind These Hazel being released to Hot AC stations and it reached number 1 so I don't think they should release it to that format. I think AC stations are a bit different. Last time I checked, it was only being played on 5 AC stations. They do tend to be slower when it comes to playing them, and I think to reach the top 5 or so the song would have to be released to that format. Because of You has huge potential on AC stations, so I think early January would be the best time.
