They don't really work, especially the victory ones. I think they should be shorter, use more instruments, more fitting scales and better melodies. The Victory1 ME has a good melody but it doesn't work as a victory ME. I've tried them all, and all of them feel off. I could already tell that they were not going to work when I listened to them. The victory MEs are incredibly depressing instead of being satisfying and the defeat MEs just don't work. At least they're free. But I don't recommend them. The Victory2 ME could be better if you got rid of the last two notes and added more instruments and changed the scale slightly. Listen to examples, practice and you'll get better.
