Template:Ai no Mama ni Wagamama ni Boku wa Kimi Dake wo Kizutsukenai Song

Unquestionably one of the band's signature songs, "Ai no Mama ni Wagamama ni Boku wa Kimi Dake wo Kizutsukenai" is not only the B'z song with the longest title but also one with a very distinguished history. Despite its massive sales and status as their best-selling of all time, the band were not certain it fit the live stage and did not perform it whatsoever between 1994 and 2003. In fact, through 2010, it had only been included for five tours. Koshi had long wanted to write a song with a long, distinct, and rhyming title like this, but even then, the song was originally only titled "Ai no Mama ni Wagamama ni" before being expanded later in production.
