JoJo's Bizarre Adventure: O.S.T Battle Tendency [Leicht Verwendbar] (ジョジョの奇妙な冒険 O.S.T Battle Tendency [Leicht Verwendbar]) is an original soundtrack enclosed with the JoJo's Bizarre Adventure Vol.4 Limited Edition Blu-ray. The entirety of the music in the soundtrack was composed by Taku Iwasaki.
In a unique naming theme, all of Battle Tendency's soundtracks are named in German. This specific one, Leicht Verwendbar, means "easy to use", a mistranslation from English into German for "Light User". A more accurate title in German would be "Lichtnutzer". The German word "leicht" means "light" as in not heavy, whereas "Licht" is "light" as in a source of illumination.
