Gloria Muliro, "Amini" (Believe). The chorus is something like:
Believe, my friend (God will lift you up)
Believe in your heart (God will lift you up)
Do not worry (God will lift you up)
Do not fear (God will lift you up)
Even if you are the least (God will lift you up)
Even if you are weary (God will lift you up)
Do not worry (God will lift you up)
Do not hurry (God will lift you up)
There really isn't anything profoundly thematic about this series; the music will be all different styles and won't have any particular link to the day on which they are posted. They're just from all over, and a reminder that Easter will be all over the place.
