I think that 13 songs would be a bit much at once..
Then again, the most we can have at once this year is 10-11 with a new single release, so..
She usually aims for 15-17 tracks.. Hopefully this year's is 17.
[It would be bad because of too much new material at once... if you read back to 'opinions of MY STORY' threads, you would find that people thought that the mass amount of new album tracks left people sort of boggled or something like that LOL]
