We loved the music as well. I have been on a bit of a quest to collect the music there.
They do sell several CD's in Zawadi Marketplace but only one of which contains a song or two that they actually play there. Other than that, I asked at the desk and they gave me a list of artists that they have compiled the resort loop from. They recommended picking these up at Virgin at DTD.
After buying several of them, the only one that has lots of the tracks I remember, is African Voices - a compilation put out by Narada. I bought this on bn.com.
This list is artist followed by song title:
Telek
-Go Ralom
-Balamaris
-Talaigu
Khadja Nin
-Africa Obota
-Embargo
-Like an Angel
-Mama
-Mzee Mandela
-Turasa
Nakodje
-Aliou Wara
-Nana
African World
-Sou
Samite
-Bring Back...Music
-Cradle with Love
-Esawayo
-Having a Good Time
-Night Stories
-Tindiba
Vieux Diop
-C On
-Mom's Jam
-Nio Koto Koba
African Voices - if you can only buy one, get this one.
-Dala
-Ekibobo
-Kothbiro
-Ngak
-Ondiek
-Tatenda
-Wasuze Otya
In the Zawadi Marketplace, they play:
Festival of the Lion King
Music from DAK
Jabula - Henne Bekker - available to buy
Wassalou (Show Me the Way)
Hope this helps!
