Man this is a good question. I would have to ride with 4. I think DIL was a great album, and honestly most of the tracks are still relevant. 4 tho, is one of those albums where you felt what Beyonce felt in that moment. The songs were emotive and honest. It felt cohesive from beginning to end. I think it was some of the most raw singing Beyonce has done. I love all 4 albums, but '4' was just an album where she expressed herself naturally without thoughts of how it would sell.
