I've just finished the last song on my list - The End of the Game by Weezer(which I thought was appropriate). So beyond the weekly DLC which everyone will add to their stats, my standings are as follows for vocals:
Disc songs score: 11,750,290 (18th)
All songs score: 578,937,398 (9th)
Gold Star Songs: 2871 (13th)
Expert Full Combos: 2871 (13th)
Now I guess I'll work on Crimson Stars, as there's nothing left to do in the main game. It's a little bit frustrating - I can see people above me on the leaderboards who are clearly worse players, but because they had the foresight/funds to grab stuff as it was being delisted, they'll always be ahead of me.
