KOMCA should be the abbreviation of Korea Music Copyright Association, which means Korea Music Copyright Association. The method of distinguishing Korean original CDs is simple. It's fake if they don't live in China, but China has their CDs. There are also some singers who live in China, but they don't release a CD in South Korea and China at the same time. They only release a CD in China. Those words or pictures printed on the cover of CD can be copied by modern high technology-; But it will be difficult. As long as you know something about Korean music, it is easy to distinguish these things. :) Q: I just don't understand.-|||| A:-||| So if you are interested in these, listen to more songs. I'm sorry I didn't give you a reasonable answer:) Q: Which one is true? Answer: the ones with the words sm and KOMCA should be genuine, but what you said is that A is unbalanced should be pirated. I don't have this on my CD. There is also a need to look at the exquisite degree of the CD, such as packaging, to see if there are lyrics or posters attached, because basically all new albums in South Korea have lyrics of posters, which is necessary and will be signed.
