Portal 1: The spiders quick movement I think fit the songs energetic start best compared to the cube and UFO
Portal 2: this part of the song felt like a slightly less energetic version of the first part just like how the ball feels like a less energetic spider
Portal 3: in this part it felt like there was an emphasize on the 4 on the floor beat which I think the bounce of the UFO matches best compared to ship and swing
Portal 4: In the last part the song feels like it loosens and I think the swing matches this perfectly with it's floaty swings wile the spider and robot are too rigid
