"Soon you gonna see you can't replace him / With cheap imi..." (Jay Z – Encore) | accepted

"All black diamonds, times were hard" (Rick Ross – Free Mason) | rejected

Could be about a diamond watch; diamonds are really hard and watches tell time.

"This is for the soldiers that see the sun at midnight, ya..." (Rick Ross – Free Mason) | rejected

This line might be a double entendre. 1. The “sun” is the bright flash from the barrel of a gun when fired at night. Ross is giving a shoutout to street soldiers. The possible 2nd meaning could be people who are optimistic.
