Shouts used in watch the throne?

[b Asterisk Asterisk]

Hey, I have a question about samples used in the album 'Watch the Throne' By jay z and kanye. In some songs (particularly n***as in Paris) ther shouts in the background, like yeahs and oh's and stuff, and they are very energetic. Any idea where to find short vocal samples like that?

 

[Major Scale]

Most dirty south rap acapellas are full of them

 

[Rekordhead]

The "yeah" which kanye uses a lot is from Mountain- Long Red (Live)
