When you reach #1 on the Top Stars list, you will be offered the opportunity to do a comeback and get the following perks:
 
  • Access to a new list status (+, as in E+, D+ ... A+), which your friends can see
  • Access to special rewards (including a permanent bonus +1 to max energy for each comeback)
  • Access to new gigs (ex. a "comeback" storyline for the first comeback) However, you’ll drop to the bottom of the Top Stars list again, so you’ll have to climb your way back to the top!
