And did you catch Toto's Africa in Rihanna's Diamonds? Bet you won't catch that one :) Catch one where you dont have to strain your ears and brain to hear something even remotely similar. The producer Benny Blanco even said in an interview on YouTube Diamonds was inspired by Africa. At 2:40 he mentions it: http://youtu.be/YnHofSA0CKE
Listen to both beats and you can hear it. I'm shocked Toto haven't sued all of them yet.
