Why do some rock pop productions tune their drums to the song?

In most of the reference mixes I am opening up lately, I am seeing that the kick drum, percussion and snares often are tuned to certain notes in the scale of the song? There must be a great effort in doing this so what is the benefit to doing so? I am especially interested in the kick drum. I am seeing a lof of the time that the kick drum is tuned to a note from the key of the song and many times it is the tonic note or the 5th.
Here is an example of what I mean. You can hear the drums alone and then with the bass guitar coming in on top
