By most metrics, Taylor Swift is the most popular musician of the 2020s, and it’s so much her era that when anyone famous voices anything even remotely disrespectful or negative about her, it’s newsworthy: Read More…..

It’s also foolhardy: Because so much of the world is on the side of the monumentally famous and successful voice of a generation, high-profile critics run the risk of invoking the ire of Swift’s legion of devoted fans, Swift’s songwriting pen, or a few days of negative media attention.

One of a handful of musicians who became hugely successful after they switched genres, the former country music star speaks up and often about whatever she feels and thinks in the form of songs, as do those who are decidedly not Swifties. She’s experienced a lot of mutually bad breakups and bad business deals, or just plain alienated other famous people for a litany of reasons.

The original version of Taylor Swift’s third album “Speak Now” hit stores and sites in 2010. The record arrived on the heels of Swift’s 2009 romantic relationship with fellow singer-songwriter John Mayer. The musicians’ relationship had a controversial age gap, as Mayer was 32 when the romance began, Swift was 19, and “Speak Now” included the song “Dear John,” a chastising of an older man for exploiting a much younger woman.

A minor chart hit in the U.S., “Dear John” found its probable intended audience — its inspiration and subject matter, John Mayer.
