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. Many times the first track is an Epic Instrumental Opener. If downloaded they generally come as separate files, and if ripped from a CD they always do. Fortunately, there is software to combine them into one file, at least if they are in either MP3 or open source formats, thus eliminating the annoyance of hearing what sounds like a song ending in the middle when playing songs in random order (shuffle mode). 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.
