IASF & 4 are worse, though Lemonade is bottom 3. You all can take your foot off DIL's neck. It might not have the strongest album tracks, but when you weigh in the amazing singles (CIL aside), it is a very, very strong album.
B'Day is her best or BEYONCÉ if you count the remixes/re-release tracks.
I appreciate Lemonade for its commentary on being a black woman in America but I don't think any of the tracks individually are as strong as the tracks on her self-titled album, which is her magnum opus IMHO.
