Beyonce fans thought Christmas had come early on Thursday with the surprise release of not one but two 10-track albums under the name Queen Carter.
Yet a closer look at the track listings revealed the "new" albums to be unofficial compilations of previously released or bootlegged material.
The two albums, titled Have Your Way and Back Up, Rewind, appeared on Apple Music and Spotify before being removed.
Beyonce has yet to comment on what appear to be unauthorised releases.
Fans expressed dismay on realising the albums were the musical equivalent of a lump of coal in a Christmas stocking.
"If you thought those 'leaked' songs from Beyonce were new, YOU'RE NOT A REAL FAN!" wrote another.
The Beyonce compilations came on the same day that nine tracks by singer SZA were uploaded to Apple Music and Spotify.
Released under the name Sister Solana, the songs on the Comethru "album" were "random scratches from 2015", she said.
The tracks, she wrote, were "def not new new" but were possibly "creative and scary".
And last month a collection of songs apparently by Ariana Grande appeared on streaming services under the title Nobody Does It Better, but they were swiftly removed and she distanced herself from them.
So what was actually on Beyonce's mystery non-albums? Here's a breakdown.
