ELT released an Ai no uta, and I think that Nanase Aikawa also released one. But it was ages ago. :\

In Japanese, "love song" can be translated to "ai no uta" (愛の歌)　or "koi no uta"　(恋の歌). This could be:

Ai no Uta (dorama), a 2005 dorama starring Kanno Miho, Tamaki Koji and Narimiya Hiroki.
Ai no Uta -Magenta Rain-, a single by Aikawa Nanase (or more specifically, the song information).
Ai no Uta (BUCK-TICK), a song by BUCK-TICK.
Swallowtail Butterfly ~Ai no Uta~, a single from Chara under the name Yen Town Band (or more specifically, the song information).
Ai no Uta (Do As Infinity) , a song by Do As Infinity.
Ai no Uta (Every Little Thing), a song by Every Little Thing.
Minihamuzu no Ai no Uta, a single by Minimoni under the name Minihams.
Ai no Uta (Nanamusica), a single by Nanamusica.
Ai no Uta (PENICILLIN), a song by PENICILLIN.
Ai no Uta (Psycho le Cemu), Psycho le Cemu's fourth single (or more specifically, the song information).
Ai no Uta (Strawberry Flower), a single by Strawberry Flower (or more specifically, the song information).
Ai no Uta (Tanpopo), a song by Tanpopo
Ai no Uta ~Jeongmal Sarang hae yo~, a song by Tsunku.
Koi no Uta, GO!GO!7188's third single.

There we go..

It's just in a coincidence imo. A lot of people have done the "Ai no Uta." :\

It's like the Japanese version of I Believe, or Crazy..
