A previously-unreleased track from Mac Miller titled Benji The Dog was leaked on the streaming site Soundcloud on Monday.

The rapper, who died at the age of 26 on September 7, 2018, following a fatal overdose from alcohol, cocaine and fentanyl, sampled the 1972 Valerie Simpson track Benjie.

The song also used a sound drop from the 2016 FX miniseries The People V. OJ Simpson: American Crime Story, of David Schwimmer as Robert Kardashian saying the phrase, 'He's always going to be the Juice.'

Miller's track included lyrics about his experiences using drugs:

'They told me don't make a promise you can't keep/All the drugs in your system, you can't sleep/How many times you had to buy a Plan B/For a girl you never bring back home to meet your family.'

He continued:

'Man, I swear this is what I dream about/Ever since my mom told me that she needs me out/Always smoke weed, causing trouble, never clean the house/But I paid her back for everything, I guess we even now.'

Sap, a producer who had worked with the late Pittsburgh native, told DJ Booth this week that Miller 'gave the fans a good amount of work' in building a comprehensive catalogue prior to his premature passing: 'The stuff he put out, that's a full career for somebody else.'

Sap said that Miller was finicky about the material he released, from what he'd amassed in the recording studio.

'It's so many records that I have, I don't even know the projects they're from,' he said. 'I feel like he was somebody that put out everything that needed to be out, you know? I feel like he gave the fans the right music.

'I'm sure a lot of fans want more Mac music, especially if he's your favourite artist.'

About a month prior to his death, Miller put out his album Swimming, which went to receive a Grammy nomination.
