Communications (now iHeartMedia), owners of the copyrighted "Wild" moniker, threatened Beasley with a lawsuit for copyright infringement. To avoid this, in February 2004, WLDW became "Wired 96.5" and the call sign changed to WRDW-FM. (The -FM suffix was necessary because of the existence of AM station WRDW in Augusta, Georgia, which is also owned by Beasley.) During its tenure as "Wired", the station would occasionally shift back and forth between Rhythmic and Mainstream Top 40, while still placing an emphasis on Rhythmic and Dance currents/recurrents, and avoiding most rock-leaning product. On October 2, 2014, Beasley Broadcast Group announced that it would trade five radio stations located in Miami and Philadelphia (including WRDW-FM) to CBS Radio in exchange for 14 stations located in Tampa and Charlotte. Because CBS already owned two AM stations in Philadelphia, Beasley would acquire WIP, which today is WTEL. The swap was completed on December 1, 2014. Shortly after the trade was consummated, WRDW-FM shifted to a more Mainstream Top 40 direction, though still favoring Rhythmic and Dance currents/recurrents. 2015-2017: Top 40 During and after the trade, rumors abounded online that CBS would flip the station to all-news, this time as a simulcast of KYW. This was partially due to WRDW-FM's continued low ratings; in the February 2015 Philadelphia PPM ratings report, WRDW-FM held a 2.4 share of the market, as compared to direct competitor WIOQ's 4.1 share. In the spring of 2015, CBS registered domain names towards a possible rebranding as "96.5 AMP Radio," joining similar stations in New York, Detroit, Boston, Orlando and Los Angeles with the "AMP" name. On April 5, 2015, WRDW-FM began running without airstaff and promoting a significant change using the hashtag #965Friday5PM to come at 5 p.m. on April 10. At that time, after playing "Motownphilly" by Boyz II Men, the rebrand to "AMP Radio" took place. The first song on "AMP" was "Get Low" by Dillon Francis and DJ Snake. The changeover also resulted in morning host Chunky and afternoon host/program director Buster being released. On April 20, 2015, WRDW-FM changed its call sign to WZMP to match the "AMP" moniker. During its tenure as "AMP", the station's ratings improved, mostly to a low to mid-3 share of the market, but did not dethrone WIOQ. In the December 2016 Philadelphia PPM ratings report, WZMP held a 3.0 share as compared to WIOQ's 3.6 share. Around Christmas of 2016, morning
