"I think the emotion that song carries makes it good. Because you have to produce around something - an emotional attachment and a feeling. The melody itself has a feeling in it. The keys, the tones, frequency, sonics, all of those have feelings in it. Like, it's the ghost within, the music itself. That's what makes the song even have a possibility of being great. The emotional connection. Because if you don't have that, I don't think you really have a song."
