Appropriate modifications were necessary; every singer had their own style that suited them, and since Britney and Christina's styles had been proven successful in my previous life, why spend time and effort exploring other directions? Of course, a singer cannot maintain one style forever, even MJ or Madonna continuously sought change, but that would be much later. First, one needed to become famous, find the right style, and solidify it.
This wasn't a concern, though Adrian focused more on the record company than the film company, after the merger with several powerful competitors, it had become one of the top second-tier companies. Especially after the launch of Britney, which was extremely popular with teens, the company was poised to level up. The company had expanded considerably, and Adrian only needed to provide some key inputs, the rest could be easily managed by them.
