ELI5 Why does singing/rhyming help you memorize? Secondly, why does it seem to help motivate younger children to do things they normally wouldn't?

I could never get my 2yo daughter to help me clean up her toys, but once i started singing 'putting your toys in the box, putting your toys in the box' it's much easier to get her to go along.

The human brain is hard wired to see patterns and repetition, it's how we hunt, gather, communicate, judge, problem solve. Patterns put our minds at ease, and make things easier to comprehend. It's actually why conspiracy theorists manage to convince themselves and others that conspiracies exist, because we look for patterns, even where their are none. 

Rhyming is patterned thought in itself. When you rhyme words together to remember something, each one is connected in a very simplistic and easy way, and it puts the storage part of our thought process at ease.
