So, I have a story for you. Today, I had this great melody in my head that I planned to use for a song. It was a great, catchy melody. A few minutes ago, I sat down at my computer, ready to bring this new song to life, when I realized something... It was this song. I kept hearing the melody from this song a month after I'd listened to it. That automatically makes it catchy, if you ask me. :P
