'Watermelon Sugar' - Harry Styles -

Harry Styles's hit song 'Watermelon Sugar' has dominated the airwaves for nearly two years now, giving fans an ample amount of time to theorize what the seemingly sweet summer track is actually about—specifically leaning towards oral pleasure. While performing onstage in Nashville on October 1, the pop star teased the crowd: "This song is about... It doesn't really matter what it's about." He continued, "It's about, uh, the sweetness of life."

'All Too Well' - Taylor Swift -

Taylor Swift made waves when she released 'All Too Well' on her 2012 album 'Red,' largely because it depicted a devastating relationship and heartbreak—and because it was believed to be about a three-month relationship she had with Jake Gyllenhaal. As part of her re-recording process, Swift released a 10-minute version of the song in 2021 and simultaneously resurfaced all those old rumors.

The song includes the lyric, "And I left my scarf there at your sister's house / And you've still got it in your drawer even now," which fans think references a scarf that the actor was spotted wearing which apparently belonged to Swift. Ironically, during the release of this song, Gyllenhaal was actually with his sister Maggie at an awards ceremony. Maggie also previously expressed confusion a few years prior on 'Watch What Happens Live With Andy Cohen' about why people keep asking her about this scarf. 

If that weren't enough, the song also includes scathing lyrics like, "I'll get older but your lovers stay my age," and, "You said if we had been closer in age maybe it would have been fine / and that made me want to die," but  Gyllenhaal never commented then and he's unlikely to comment now.
