What is this type of music?

[PepsiMcPringles]

Hi, I like this type of music, where there are no instruments, but the vocals are doing the beat in the background, basically where it's all vocals rather than vocals paired with drums/guitar/keyboard etcetc. I just love how cool it is that those sounds can be produced from a human

Here's what I mean:

Basically any of the soundtracks in Crash: Twinsanity

and I recently found this type in a Glee song my nephew was playing haha:
Glee Cast - Yeah!

A bit hesitant to put this one on, because it's more beatboxing, but this is the first song I came across as a kid which is mostly just coming from his voice, and I always found it really cool:
Only Human - SNAP!

They can't be all classed as beatboxing, can they?

Any help and similar songs would be appreciated

p.s I'm not allowed to post the links for the music vids, sorry for being a noob, lel
