2AM's Changmin is now officially certified as a composer.

Changmin posted to Twitter on the 19th: "I'm composer Lee Changmin. Kekeke. I got it~," and attached a photo of his 'copyright trust certificate'. The 'copyright trust certificate' is granted by the Korea Music Copyright Association for composers who want to make sure their work is copyrighted and protected.

The 2AM member has previously received recognition as a singer-songwriter for composing songs, such as "To Love Again" and "I Love You I Love You", for his group.

Fans commented, "Lots of money for copyrights", "I'm so proud", "I thought you were only a good singer, and now you're a composer too? An idol musician", and "You're becoming like your teacher J.Y. Park. In terms of both looks and talent. Haha".

Congrats to Changmin!
