The $620m (Â£395m) he made before tax means he has topped Forbes' list of the biggest earners in music in 2014.
Not only that, but he has now also got the Forbes record for the highest earnings in a single year by any musician.
The majority of his cash has come not from record sales but from Apple's purchase of Beats, the company he founded, for $3bn (Â£1.9bn).
Best known for their headphone range, Beats also makes technology used in car audio systems and has a music streaming service known as Beats Music.
Priced about $300 (Â£191) in the US, Dr Dre, if he were so inclined, could buy more than two million sets of his Studio headphones with his earnings.

One pilot died and another jumped clear as the helicopter crashed during an aerobatic display by the elite Berkut squadron in the Ryazan region, about 170km (105 miles) south-east of Moscow.
The Russian military has blamed the crash on a hydraulics failure.
There have been six other Russian air force crashes in recent weeks.
The two-seat gunship was performing stunts and firing flares with three other helicopters. It then began to spin rapidly, before falling to the ground and bursting into flames.
Its pilot Lt Col Igor Butenko was killed. His son told Russian media that the accident was not due to pilot error.
"There are situations when it's impossible to survive no matter how well-trained the pilot is," he told Lifenews.
The Russian defence ministry says the condition of the other pilot's condition is "satisfactory".
There were no injuries to spectators at the air show.
An investigation has been launched into the cause of the crash, although the surviving pilot has said that a hydraulic failure was the cause. The country's fleet of Mi-28s will remain grounded until the investigation is completed.
The Mi-28 is an attack helicopter widely used in Russia, as well as countries such as Iraq and Kenya.
At least five people have been killed in recent military aviation crashes.
In the past few years, the air force has received hundreds of new helicopter and planes as part of a programme to modernise and reequip Russia's military.

Henrique Capriles said 37% of the 195,000 signatures needed to trigger the next phase of the recall referendum were collected on the first day.
Those who endorsed the petition have until Friday to have their identity checked.
Mr Maduro's term runs until 2019.
But the opposition wants to oust President Maduro, whom they blame for Venezuela's economic problems, before the end of his term.
Venezuela is in the midst of an economic crisis which has brought the South American country to the brink of collapse.

It has the world's highest inflation rate and chronic shortages of basic food and medicine.
Mr Capriles said the massive presence of voters on the first day of the validation process was a clear sign that Venezuelans wanted a change of government.
"What we saw today were queues across the country," said Mr Capriles on Monday night. "That's a warning for Maduro."
Those who endorsed the petition will have until Friday to have their identity cards and fingerprints checked at centres set up by the National Electoral Council (CNE).
The petition had almost two million signatures but election officials said 600,000 of those were fraudulent.
Only 1% of the electorate, or 194,729 voters, however, need to endorse the referendum in this first phase.
Mr Capriles said 71,557 signatures had been authenticated on Monday alone.
But the opposition still has to overcome a number of hurdles before a recall referendum can be held.
If enough signatures on this initial petition are validated, opposition leaders will have to hand in a second petition signed by almost four million people.
Only when the electoral authorities have established that the requirements have been met on that second petition will the recall referendum be held.
