While many people shared the tracks on social media, some said a Google Drive link containing the full 17-song playlist was uploaded.
Swift fans said they will wait for the official announcement.
The singer announced her 11th studio album at the Grammy Awards.
On X, formerly Twitter, some Swift fans filled the site with fake links to hide the leak and prevent it from spreading, while saying they would not listen to the music before the scheduled date.
"Taylor and her team have planned and worked so meticulously on the release of this album, don't disrespect and ruin it," fans wrote.
