Atlus is a super stylish and talented development studio, making the critically acclaimed persona 5 and shin megami tensei games. They are accustomed to dealing with difficult themes in a fun and powerful way, such as in Devil Survivor, Digital Devil Saga, Persona and Shin Megami Tensei. They (Atlus) also known as (Index) were purchased by Sega. Sega owns the rights to the franchise Jet Set Radio, but has clearly given up on making anymore entries. Why not let the stylish company make the stylish game? Both Atlus and Jet Set are known for having super snazzy music, so i'm sure they'd make an amazing soundtrack for the game as well.
