Midas is a person from Greek Mythology. He was the son of Zeus (Kind of the Gods). His story is that he once helped a friend of a god (Dionysus) and in return the god granted him whatever wish he wanted. Midas asked for the ability to turn everything he touched into gold. You can also see another reference to Greek Mythology when Haneul turns the guy into stone and the snakes that appear, which is what Medusa can do. The lyrics talk about just one touch, referencing Mida's story of turning things into gold with just one touch. People also use the phrase of having "Mida's Touch" as a way of saying everything someone does is gold or really good, so you can say that Kiss of Life has the Mida's Touch since all of the music they "touch"/make is really good lol also you should react to their other song "Nothing" if you haven't already, it's also "gold" lol
