It appears not even the members of 'NSYNC knew they had an album dropping today.
The two-disc Essential 'NSYNC album features all the favorites along with a few less recognizable tracks.
Both the former boy band's Twitter and Lance Bass tweeted about the surprise album, admitting they were just as in the dark about the release as their fans.
"I love when the record label doesn't even tell you they are releasing a new 'NSYNC album tomorrow ! #TheyCare," Bass, 35, wrote.
As of early Tuesday morning, Amazon had been selling quite a few copies of the newly released album. The site read: "Only 1 left in stock (more on the way)."
