"Gotta Work" is a song by American R&B singer-songwriter Amerie, and is the second international single from her third studio album, Because I Love It (2007).

It samples Sam & Dave's 1966 song "Hold On, I'm Comin'", written by Isaac Hayes and David Porter and originally recorded by Reuben Wilson.

Amerie called the sound of the song "'go-go soul'", saying go-go "[is] like really strong black coffee, some people can't ingest it in its purest form.

Blues and Soul Magazine said the song "sounds like it's come from the same factory of hits as most of B's output ... 'Crazy in Love' meets 'One Thing' [sic]", but that it "treads that rare fine ground between club-friendly sing-a-long anthem and credible soulful territory; its bold and brassy orchestral instrumentation and clattering percussion pushing it along nicely.

[4] The Daily Mirror wrote, "An old superpowered Stax riff will never let you down and there's a particularly supercharged one at the centre of ["Gotta Work"] ... Amerie sweats and grinds in the funk engine room, whipping up a lather and doing the song she has sampled a service.
