Pusha-T is known for his streetwise raps, but his most popular bit of songwriting doesn’t have his name on it. Back in 2003, Pusha penned the iconic “I’m Lovin' It” jingle for McDonald’s. In a new interview with the Drink Champs podcast, he revealed that it’s one of his biggest regrets because he didn’t secure any publishing rights for the song.

“I took a super L,” he said about the jingle. “Just upfront, no publishing. Shoutout to [former music executive] Steve Stoute, he gave me the check and I was like ‘Ahhh great,’” Pusha said. Although he received $500,000 for the song, he realized in retrospect that he should have earned far more due to its enduring popularity. “I want artists to know that part. Keep your publishing. That check will be nice, but ‘I’m Lovin’ It' been running for how long now? I did This in ‘03. Who knows what it would have been,” he said.

Pusha did, however, note that he secured publishing rights on another popular fast food commercial. “The get back is real. I also own 40 percent of the Arby’s commercial. You live and you learn.” He’s referencing the end of the chain’s recent commercials, with the slogan “We have the meats.”

The instrumentals are sampled from the 2014 song “Burial,” which he released with U.K. EDM act Yogi:

Elsewhere in the interview, Pusha revealed that his verse on “Feel the Love,” which opens Kid Cudi and Kanye West’s Kids See Ghosts album, was recorded just hours before they released the album. “I’m on a flight to Montreal. [Kanye] hits me, ‘Yo, I need a verse, can you go to the studio right now?’” Pusha recalled. “I’m like, ‘I can’t.’ He hits me back, ‘No, I need you to go to the studio right now.’ Mind you, the album is coming out in 6, 7, 8 hours. I’m about to do a show. I’m in Montreal. They book a studio. Alright, cool.”
