The first is face the music. It means to accept the results of what you have done.
Here is an example from a Reuter's news report.
Britain's highest court had ruled that former Chilean dictator Augusto Pinochet was legally arrested.
Opponents of General Pinochet welcomed the news.
One of them said we have waited for years for this man to face the music.
No one is sure how the expression began.
One story is that it came from a military ceremony held when a soldier was forced out of an army.
The buttons were cut from the soldier's clothing.
He was put on a horse facing the back of the horse and let away.
As he left he faced the music of a military band and the soilders he had served with.
