Do you like RnB? Because Beyonce's Dangerously In Love is an unforgettable album.
Some of my personal favorites from 2003 to 2004: John Mayer- Your Body Is A Wonderland, Coldplay- Clocks, Black Eyed Peas- Where Is The Love, Madonna- Hollywood, Maroon5- This Love, Black Eyed Peas- Let's Get It Started.

I can't think of any more songs right now.
