Kirk Hammett of Metallica has drawn attention for wearing a T-shirt referencing Taylor Swift in a conspiratorial light, sparking backlash from Swift fans, while also performing at book events where he discussed his guitar collection and jammed with bandmates. He previously faced criticism for a comment about pop music and for a fall during a Dublin concert, which he downplayed humorously. Hammett also expressed admiration for a Fleetwood Mac song as an influence on heavy metal and offered to return a guitar he borrowed from Neal Schon.
