Anyone paying attention saw J.Lo announce this tour in December of last year, so clearly the Motown tribute did not have some secret ulterior motive. Why is anyone mad that J.Lo infused some of her own culture in the performance? Don't we want people to be their true selves? No one complains when black artists perform remixes of classics by all different artists. Jennifer didn't even change the music. The salsa sound was added as a riff. Look at Nicki's appropriation of Chinese customs if you want to discuss a real example of someone doing something wrong with music and culture. Always the biased ones complaining.
