Busta Rhymes’ 2009 release “Hustler’s Anthem ’09” features T-Pain.
The track appeared on Busta Rhymes’ eighth studio album, Back on My B.S., and was issued as a single through Universal Motown. T-Pain’s melodic vocals and trademark Auto-Tune-influenced style provide a strong contrast to Busta Rhymes’ rapid, forceful rap delivery.
A common mix-up comes from versions and remixes of the song. The standard release is credited to Busta Rhymes featuring T-Pain, while some expanded or remix versions involve additional artists, including Lil Wayne. Those extra collaborators do not change the answer for the original release named in the question.
The collaboration also reflects T-Pain’s prominent role in late-2000s hip-hop and R&B. During that period, he frequently appeared as a featured vocalist on rap singles, helping define the era’s blend of hard-edged verses and electronically processed hooks. “Hustler’s Anthem ’09” is therefore best identified by its official primary feature credit: T-Pain.
