I don't how people just class the IASF album as pop?
With jazz influences in Single Ladies, Hello, Ego then the operatic tone in Ave Maria, to the rock edge in If I were a boy??

Without doubt, was DIL epic. 5 major hits. Crazy in Love, Me myself and I, baby boy, Dangerously in love etc.. That brought her onto the scene.

Bday was a nice follow up, with memorables like deja vu, upgrade you- but not as outstanding as the others.

4 was emotional and intimate..some songs like Rather die young I didn't get, and took a while to grow on me.. End of time - classic. I miss you - on repeat for days (wish it was longer)
But personally IASF was iconic and that converted me from a liker to a fan! I mean it was so well crafted, produced major hits like If I were a boy, Halo, Sweet Dreams, Single ladies, Diva etc
It fully deserved all the grammys it won.
