Out of curiosity, fans searched up Chanyeol's name on the official website of Korea Music Copyright Association and found that two names exist under the same ID code. One is Park Chanyeol and the other is LOEY. Fans also noticed that LOEY is named under several songs that were composed by the members of EXO. As you can see, LOEY is listed as a composer for the 2016 SBS Power FM logo song by Suho, Baekhyun, and Chanyeol.

Fans assume that LOEY is the last 4 letters of Chanyeol's name- 'YEOL'- spelled backward. Many are finding his name very unique and encouraging LOEY to do more wonderful composing.
