He peaked with confessions cause everything he puts out gets compared to it. Bad Habits to me sounds like a Confessions album track. Despite long breaks between albums he never seems to reinvent himself in any career defining ways. He's just barely legacy act material imo cuz he's fans are currently DOA just like his newer music. Legacy acts need STRONG albums and singles to stay relevant

Usher and Mariah are both proof your only as big as your last hit
