Taylor Swift and Beyoncé Avoided a Collision on the Charts. (Again.)

In February, Taylor Swift took the stage at the Grammy Awards to accept the prize for best pop vocal album. After dutifully thanking the Recording Academy and her fans, she got down to business: “My brand-new album comes out April 19,” she said, in a surprise announcement revealing “The Tortured Poets Department.” It was a heads up for her loyal followers, as well as anyone else in the business with a spring release on the radar: If you want your new album to debut at No. 1, don’t release it on April 19. Or April 26. Or May 3, for that matter.

A week later, following a teaser during a Super Bowl commercial, Beyoncé also dropped news of a new album: “Cowboy Carter” would arrive earlier than “Poets,” with breathing room, on March 29. Another pop powerhouse in the Grammy audience made her own announcement in early April: Billie Eilish will unveil her forthcoming third album, “Hit Me Hard and Soft,” a month after Swift’s release, on May 17.

Beyoncé and Swift, the 21st century’s pre-eminent pop stars, have often been cast as competitors if not rivals, a story line partly rooted in misogyny and amplified by dueling fan armies filled with stans, or superfans.
