The unsealed documents include sales and marketing "playbooks" from 2007 through 2010. Politico, however, published the 2010 playbook in March.
One of the playbooks informed sales people that the last song played before an instructional video in a seminar "should be the Apprentice Theme Song: For the Love of Money by the O'Jays."
The seminar referenced was a free 90-minute presentation open to the public called "Fast Track to Foreclosure."
The seminar, which aimed to drum-up interest for Trump University courses, discussed "the current trends of the real estate market and ways to still make money."
Sales people were advised to watch the body language of the audience members during the presentation to identify which viewers were "most likely to buy," encourage them to join, and then collect payment.
"Full payment of $1,495 must be collected before paperwork is submitted to Trump U," the playbook reads.
The documents were unsealed as part as of court decision by Judge Gonzalo Curiel, whom Trump has called a "hater" and suggested his Mexican heritage makes him biased in the case.
Before the documents were released on Tuesday, New York Attorney General Eric Schneiderman slammed Donald Trump and his eponymous Trump University as "phony" and "shameless."
Trump remains enmeshed in multiple lawsuits filed by former students of Trump University and faces a third fraud suit from Schneiderman, which likely won't go to trial until after the November election. The suits accuse Trump of defrauding students into paying thousands of dollars for worthless classes on real estate and investing.
Trump and his lawyers, however, have continually defended the for-profit university, citing stellar student reviews. Some students, however, may have been pressured into writing them, according to The New York Times.
