Watch: Taylor Swift gets candid about her all-time favourite song

Taylor Swift recently spilled her all-time favourite song which she ever recorded over the years.

The Cruel Summer crooner was asked to share a list of her top five songs during an appearance on Wednesday's episode of The Late Show With Stephen Colbert.

Taylor opened up that her ranking "are constantly changing" and therefore, she would need "a little time" to get back to him.

However, the singer, who is currently promoting her The End of an Era docuseries, did mention the song she would like to place on the top of her list and surprisingly, it's a fan favourite as well.

"I think number one is All Too Well - the 10-minute version," said the 35-year-old while speaking to Stephen.

Another track she's "obsessed with" is The Life of a Showgirl, "the whole album" in general.

"I cannot really any of the other, except I will say somewhere in the list, it's going to be a song called Mirrorball from the Folklore album," explained the songstress.

Taylor pointed out that for now, she didn't have her definitive top five but some day she would give an "update" after going through songs in detail.

Meanwhile, the first two episodes of End of an Era docuseries will drop on Disney+ alongside her concert movie, Taylor Swift: The Eras Tour: The Final Show, tomorrow on December 12.
