I'm going to say no even though its Brintey's best album. I just don't think it has the "longevity", groundbreaking factor for it to be considered a classic. I also don't think it has aged well. Maybe it got overshadowed by her personal life at the time, I don't know.
To those worried/annoyed about this album going first, don't worry it'll change EVERYDAY. So tomorrow will be another artist.
