I would love it if he tried with ska, pop rock, etc but still keeping that young guy vibe. Because he will NOT happen with those Bieber wannabe songs he's doing.
He needs to do teen pop, which suited him & his looks [What About Love Banga Banga]. Trying to grow up so fast with this rnb thing is Not the best thing for him. Even if he loves that kind of music.
Also his team/label needs to promote him more.
