This is a personal opinion, not racist and like attacking the fans.
I love Jero and all, I even bought his album cause his singing is pretty good. BUT
He just doesn't appeal to me as a "hot" black guy that I often see. Like ripped abbs or over confident attitude.
Jero just comes off as a "cute" black guy which is kinda lame cause he got so much going. I'M not asking like for him to do a Japanese AXE or Japanese Old Spice Commercial (but god please that would be so interesting) but just Jero had the potential just wasn't used probably cause of his traditional genre.
