Template:Pleasure'91 ~The Pleasure of Life~ Song
"Pleasure ~Jinsei no Kairaku~" is the title of an evolving song by the band, first released in studio as a B-side. Since its debut with the 1991 edition, the lyrics have steadily changed at regular intervals to convey the life of the lyrics' aging protagonist, with the title including the year in which it was created such as with "Pleasure'91". As of 2012, there are seven editions of the song, three of which have been released on CD: the B-side here for "LADY NAVIGATION", a re-recorded version requested by fans for B'z The Best "Treasure" in 1998, and and another re-recorded update found on B'z The Best "ULTRA Pleasure" in 2008. The rest are available for home viewing on corresponding home video releases. A version of "Pleasure" has been played at every Pleasure LIVE-GYM to date apart from the 1993 and 1997 editions.
