music:N.A.S.A feat. Kanye West,Santo Gold and Lykke Li-Gifted

I discovered this track by chance when I was reading about the arist Lykke Li and I've no idea how this collaboration came about cause I've never heard of N.A.S.A till today,and Kanye West,Santogold and Lykke Li are totally different artists on their own.How I love it when musicians/singers of different genres come together.
