WAMJ (107.5 FM, "Majic 107.5/97.5") is a radio station broadcasting an Urban AC format. Licensed to the suburb of Roswell, Georgia, it serves the Atlanta metropolitan area. It first began broadcasting in 1997 under the call sign WTHA. The station is currently owned by Radio One, via licensee Radio One Licenses, LLC.
The station broadcasts from studios at Centennial Tower in downtown Atlanta, and transmits from atop 1050 Crown Pointe Plaza, a high-rise building just barely on the Dunwoody side of the Perimeter Center edge city north of Atlanta. Issued in November 2008, it has a permit to move to its own tower on the south side of Peachtree Industrial Boulevard ( Georgia 141) and north side of Buford Highway ( U.S. 23 / Georgia 13) between Doraville and Norcross. This is along Jones Mill Road at Mechanicsville Road in the Mechanicsville community (not to be confused with the Mechanicsville neighborhood in Atlanta).
