It's been a while since I played the original CT, so I guess I didn't notice before or I had just forgot. I noticed when re-playing it on the DS that whenever you get Robo on your team, the music that plays is similar to "Never Gonna Give You Up" by Rick Astley. I've shown this to several of my friends and they think the same as I do, so if you have a method of testing this or if you can find it on Youtube, please do post it somewhere in this thread so the truth can be heard!
