Bruno Mars and his latest single "That's What I Like" reached No. 1 just several weeks ago on the Billboard Hot 100 and was bumped a week later when DJ Khaled's "I'm the One" took over for one week. However, Mars rose to the top of the Radio Songs chart and is enjoying a third week as the most heard song in the country.

After rising 2-1 just three tracking frames prior to the May 23 update, Mars collected another 173 million radio impressions in an all-genre format--any station that plays the track. It hasn't dipped but a mere one percent and has no signs of being dethroned unlike the single week lead on the Hot 100 (Mars has spent three weeks at No. 2 since his rise to the top). Additionally, "That's What I Like" is the chart topper on Hot R&B Songs for a 14th week and Hot R&B/Hip-Hop Songs for a seventh non-consecutive week.

In its second week at No. 1 on Radio Songs, "That's What I Like" garnered 175 million impressions which was up one percent over its initial rise to the top. In the tracks first week as the most heard song, it earned 172 million impressions, gaining by four percent.

"That's What I Like" is Mars' seventh radio No. 1 and ties him with Usher for a male artist. Mars and Usher are tied with Katy Perry for third overall with Mariah Carey having 11 radio No. 1 hits and Rihanna having the most with 12.

Unlike streaming and sales being tracked Friday through Thursday, airplay is tracked Monday through Sunday to give a more current reading of the Hot 100 upon Tuesday's refresh.
