Oh! One True Love

'''Oh! One True Love''' is the 61st track in the UNDERTALE Soundtrack. It plays during the mock opera scene with Mettaton near the end of Hotland.

The entire scene is a parody of the iconic "Aria de Mezzo Carettere" from Final Fantasy VI. As such, this song mimics many of the styles and instrumentation used by Nobuo Uematsu's compositions.
