Homelander is signing up (...under John Doe, not Homelander, as much as that pains him). His singing voice is solidly average, but as a seasoned reality TV star he's mostly interested in the chance to come off as charming and lovable on camera even if he doesn't get very far. Apparently some people aren't prepared to have their privacy violated at any given time, but he's not one of them. Bring on the cameras!
