i can't but feel Bey is prepping us for something AMAZING to come.
She released "Countdown" and "Party" as the Pregnancy-singles because they require less work since they are such obvious hits (wether or not the charts agree). With this anthology she included videos for songs like "1+1" "Dance for You" and "Love on Top", all good songs, but too generally opposite of radio-expectancy so they are sued to keep the fans happy.
Once the pregnancy is over with, "I Was Here" will be the ballad that will dominate. Able to perform at her peak, and bouncing off baby-born-promo, "I Was Here" will be amazing and a baby-anthem.
Following the "I Was Here"-comeback-from-pregnancy, "End of Time" will be released and will slay with epic videos, choreography and AMAZING performances!
Following that will be the dieing-down-phase with the release of "Schoolin' Life" which will be accompanied by a pretty sweat video but will not feature any performances, via-"Beautiful Liar".
as we can tell at this point, King B has a masterplan that will enslave the entire human race, and I for one can not wait to participate in it :]
