Salute the Sample is my favorite show on LL Cool J's Rock the Bells radio on Sirius/XM. This one explained a lot for me
I always thought that Jennifer Lopez's "Get Right" didn't give sample credit to Maceo & the Macks "Soul Power '74". But they didn't sample it directly, they sampled a song by Usher that sampled it.
So here's the original from Maceo & the Macks. Produced by James Brown.
Rich Harrison produced Usher's "Ride" in 2004 but it was left off his Confessions LP for some reason.
So instead he took the beat and used it on Jennifer Lopez's hit "Get Right" the next year.
