The Beatles’ classic “Sgt. Pepper’s Lonely Hearts Club Band” is being remixed for Apple Music’s Spatial Audio — again. Although a surround-sound mix of the album has been available since the feature debuted last month, producer Giles Martin says he doesn’t like it. So he’s remixing the entire album to fit the format and plans to replace Apple’s current version, he says. “I’m actually going to change it,” Martin says. “It’s good, but it’s not right. It doesn’t sound quite right to me.” He says he hopes to have the new mix finished by the end of the summer. Do you have a problem with classic Beatles music being tampered with? What’s the best remix you’ve heard?
