When users searched the song it could be found on top of Lostprophet’s charts. The song’s artwork was a screenshot of Canadian cartoon Scaredy Squirrel with the Lostprophets logo superimposed.

The song also reportedly appeared Swift’s own Spotify page, which only features the singer’s contributions to soundtracks since she removed her music from the streaming service. The Lostprophets version of the song is said to have been online for around a month before making it on Spotify and was described as “the last song they ever recorded”.

The song is also available for purchase on both iTunes and Amazon. Speaking to the Guardian a Spotify spokesperson said the situation was “very weird”. “The track in question was delivered to us by a provider, whose responsibility it is to ensure that content delivered to Spotify is fully licensed and in compliance with our Infringement Policy.”

“We take the integrity of our catalogue very seriously, and will immediately remove any content that is found to be incorrectly licensed or attributed to the incorrect artist or composer,” the spokesperson added. “The track was taken down as soon as it was discovered (3 days after it was delivered), and we will be taking the matter further with the provider who delivered this track.”
