Yet another audio recording of Michael Jackson was recently played for the jury overseeing the involuntary manslaughter trial of Dr. Conrad Murray. On the recording, Jackson can be heard begging for propofol, the anesthetic the singer was addicted to that he and Murray often referred to as "milk."

According to People, Jackson told Murray "I’d like to have some milk. Please, please give me some," and these were among the pop singer's last words. On the recordings -- which were from police interviews that authorities conducted with Murray on June 27, 2009 -- the singer's last few hours are summed up, including this direct quote from Jackson.

Apparently, Jackson couldn't sleep without the medicine and Murray admitted to giving the pop icon small doses of propofol nearly every night to help with Jackson's insomnia. Murray also said that he refused to give Jackson more than 25 mg of the anesthetic, which is usually administered during surgical procedures (Murray has come under fire for administering the medicine so freely in someone's bedroom), due to the fact that he was taking other prescription drugs.

Murray said propofol was the only medicine that helped Jackson sleep, and that he "constantly cautioned [Jackson] that it was an artificially induced sleep and he needed to go back to a natural pattern of sleep" and eventually "be on your own, with milk and cookies."

Also, Jackson would apparently put pressure on Murray to give him the medicine frequently. The singer was preparing for his This Is It world tour, and he advised Murray that he would not be able to perform if he was tired. "He complained, he was going to have to cancel the (rehearsal)," Murray says. "It would not satisfy his fans if he wasn’t rested well."

The prosecution is arguing the Murray showed negligence the day of Jackson's death, as he failed to monitor the singer, who died from an overdose of propofol. However, the defense is arguing that Jackson took a lethal amount of the drug by himself when Murray wasn't paying attention.

"I love Mr. Jackson, he was my friend and he opened up to me in different ways and I wanted to help him as much as I can," Murray also told police officers on the audio recording from 2009. "I was trying to wean him off the propofol."
