I wonder if he will ever comeback to music again. He have some decent success with his underwear and swimwear. Most likely because he is good looking. Imagine the same brand, the same name and the same swimwear. But if Steve was an average looking man who was not muscular, he would not have the same success. No doubt about that. His good looking body and face represents a big part of his success. And he knows it. He use his look at his advantage.
He knows that his music is more niche. He is self produced. So he doesnt have a big record deal. He is not a niche singer just for being gay. He is niche because he is not signed with a big record label. Like Sony Music for example. If he was signed with a big label, then he would have a potential to have a better career as a singer. Maybe he just doesnt have big ambitions for music. He can sing. He have a decent voice. But for some reasons, he didnt tried to get a big record label deal. Calum Scott is a quite successful gay singer who is signed with a big label. So Steve could also be as successful if he was signed with a big label.
