There are some 'country purists' that have a real issue with their artists collaborating with those that are outside of the country genre. To them I say, 'get over it.' It's time to move on and accept that every artist has influences and interests that span outside of their own world.
Chris Stapleton just teamed up with two mega stars in the pop world (Ed Sheeran and Bruno Mars) for what is sure to be an enormous hit. Personally, I love this song, and I think it satisfy the musical needs for just about everyone. If this is your first time hearing it...you're welcome.
