This album, Hesitation Marks - Nine Inch Nails, suddenly disappeared!
The rest of their discography is still there, including the Deezer playlist "100% Nine Inch Nails" in the screenshot above which references this album.
Please provide a valid answer. It can't be the record label or artist as this was an album that used to be on Deezer, it's not a new release, and clearly the rest of their content is on Deezer.
Deezer had a similar problem for over a year about the album Meliora by Ghost, despite having their whole discography and a 100% playlist and even Deezer exclusive content for that band.
Looking forward to a quicker fix
