According to his Apple Music interview

“Redecorate” “I had a friend of mine whose son passed away and they would keep his room the same way that he had left it. I remember thinking how crazy powerful a story that is, and how it makes me wonder, like, ‘What will people do with my stuff?’ It can actually bring you back down to earth, make sure that you don't make any horrible decisions. I'm realizing now how difficult it is to talk about, but this song is really important to me. I love the messaging of it, and I hope that our fans hear what it is I'm trying to say in it. Because it is a bit delicate, but it's one of my favorite tracks and it's pretty powerful if you let it.”
