In the past, Pusha T worked with McDonald’s to pen their storied “I’m lovin’ it” jingle, which he says he failed to get the publishing rights for.

The jingle has been used worldwide, and the brand continues to use variations of the jingle in their current advertisements. Now, Pusha T has some words for the brand he formerly linked with in a new “spicy diss track” on behalf of Arby’s, who has a new fish sandwich on the way. Arby’s dropped the diss track geared at McDonald’s, with Pusha T firing off bars directed at McDonald’s Filet-O-Fish sandwich. While speaking to Rolling Stone, Pusha revealed why he came at the brand he once worked with.
