あいのうた
The single was released in three editions, with each edition carrying different lives for the third track. Standard CD and CD+DVD editions held "XXX" and a live version of "Ai no Uta" to couple the a-side; fan club editions replaced the live of "Ai no Uta" with a live version of "All for you"; on the Hibiya Yagai Anniversary Edition, a live version of "LALALALALA" was used for track three.
