The record company is reported to have accidentally started selling high-quality downloads of the LP on Getmusic.au earlier in the week.
The mistake was only picked up a number of hours later by which time the full album had already spread across sharing platforms online, according to Rolling Stone.
The band and label have both declined to comment on the issue, however the entire album is now being streamed on their MySpace page and on Spotify.
No Line On The Horizon is released on February 27.
