I just wanted to give everyone something to think about.
If you have not finished your Blitz trophy's yet, since the fix is applied to your account at 1000 songs. Your stars are wiped from "your system" so like me for example I had not getting gold stars on all the Blitz songs. Once I played the songs I knew I had left to play I got no trophy... My system did not show my gold stars, but the server does.... I had to reply all my Blitz songs in order to unlock the final trophy I was missing.
So if you have not finished all your trophy's and your getting close to your 1000 songs,
my advice is to complete them first.
