Gotta Work by Amerie

"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. The sample used is from a cover version by Erma Franklin, off her album 'Soul Sister' (1969). 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."This song is featured at the end of the 2009 action film Fighting.
