TVXQ's Yunho, Super Junior's Donghae and Eunhyuk, EXO's Kai and Lay and SHINee's Taemin and Minho under the project name S. M. The Performance released a Korean version, featuring the vocals of Taemin, Donghae and Yunho. This version was released on December 30, 2012 by S. M. Entertainment and the proceeds were given to charity.

Livetune had originally remixed the song as a fan of Zedd's music and Zedd was impressed with the result of the remix and asked for it to be included in the Japanese release as a bonus track.

1. spectrum

   A spectrum is a condition or value that is not limited to a specific set of values but can vary, without steps, across a continuum. It can represent a range of different positions, opinions, or choices available between two extreme or different points. This term is used in various fields like physics, where it describes all possible frequencies of light or sound, and in medicine or psychology, to describe a range of symptoms or behaviors, as seen in the 'autism spectrum'.

1. Spectrumnoun

   an apparition; a specter

2. Spectrumnoun

   the several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. See Illust. of Light, and Spectroscope

3. Spectrumnoun

   a luminous appearance, or an image seen after the eye has been exposed to an intense light or a strongly illuminated object. When the object is colored, the image appears of the complementary color, as a green image seen after viewing a red wafer lying on white paper. Called also ocular spectrum

4. Etymology: [L. See Specter.]

1. Spectrum

   A spectrum is a condition that is not limited to a specific set of values but can vary infinitely within a continuum. The word saw its first scientific use within the field of optics to describe the rainbow of colors in visible light when separated using a prism; it has since been applied by analogy to many fields other than optics. Thus, one might talk about the spectrum of political opinion, or the spectrum of activity of a drug, or the autism spectrum. In these uses, values within a spectrum may not be associated with precisely quantifiable numbers or definitions. Such uses imply a broad range of conditions or behaviors grouped together and studied under a single title for ease of discussion. In most modern usages of spectrum there is a unifying theme between extremes at either end. Some older usages of the word did not have a unifying theme, but they led to modern ones through a sequence of events set out below. Modern usages in mathematics did evolve from a unifying theme, but this may be difficult to recognize.
