i dont think radios care about the content of the mv... MR kind of music videos are made all year round and they still play those songs... remember we dont talk anymore? tragic video but massive hit.. the song is good and it will smash based on it.. hope the views increase with time because its a grower....
also there are like 4-5 MR performances on her vevo so maybe the gp is confused which one is the official video and the views are getting split....
The only YouTube 'payola' that exists is putting the video under the suggested list of every other video that exists. No one checks the playlist you're talking about.
