I feel like no one did this:
Million Reasons is now available in the Top 40 RateTheMusic survey.

It is easy, all you have to do is sign up and select "Top 40" as your favorite music type. Then complete the entire top 40 survey, it takes like 5 minutes. Give Million Reasons a "Like it a lot" rating, and give all other songs "Like it some" or below. Also, make sure you check "No" to the "not tired of hearing this song" question.
If anyone remembers from 2013, we did this for Applause and it was number 1 on this survey for weeks which helped it tremendously.
Mediabase owns Ratethemusic and they use the data collected from the surveys to decide which songs should be played and added to radio.
