Siamese Twin Songs (or if you prefer Conjoined Twin Songs but it doesn't have the same ring) are those which are separate, consecutive tracks on an album where the first one leads into the second as if they were one song. If the first is played without the second, it sounds as if it has been cut off in the middle. If played on the Radio they are almost always played together. A very distant cousin to the Cliff Hanger. Also compare Fading Into the Next Song. Not to be confused with "Siamese Twins Song" from Big Fish or any other songs with the words "Siamese" or "twins" in the title.
