Not to be a fanboy or anything, nor am I trying to justify him as a particularly good artist, but I think he's respectable, especially when compared to a lot of today's artists.
On his latest album, he either wrote or co-wrote all of the songs (except Beauty and the Beat). He was actually the main writer on 10 of the album's 13 songs.
And he is talented singer. A bit of a strange nasally sound right now, maybe due to being in-between the shift of a high voice to a lower voice, but the talent is still recognizable. He was discovered on Youtube as a singer, not some sort of premade industry manipulation.
As for the looks department, he must be pretty good looking considering 90% of his fanbase wouldn't like or know him if he was ugly.
Okay, you got me. I'll put him right up there with Bobby Sherman, The Archies, Tiffany, a-ha, Tubbawumba, and the others who changed the course of music history...
