Yes he write ALL of his own songs and Co-Writes his songs he also writes songs for other people to and he is a music producer! he is sooooo talented i luv him!:D YES!
He either Co-Writes or other people write songs for his albums. He does NOT write all of his own songs, lead guitar parts, percussion parts, bass guitar parts, piano parts etc... because he can't play any instruments. All he can do is sing, and he can barely do that.
No offense to people that do love him, I understand I used to obsess over him too. I just moved on to better bands and artists. He annoys me now, with his "r&b" scene now.
