Motions is about going with the flow of tough times. The lyrics may be sad but it sounds chill/laid-back.
GAT creates many chill songs that display different emotion but often switches up the tone in his music as well. GAT makes music that anyone can listen to and have a variety of emotions to pick from.
One of the reasons GAT creates music is to help people through tough times because he knows the feeling of going through them, himself.
