What is the difference 言う vs 言わせたい?


I was looking up a lyrics for a song that has the lyrics

[code]

    君の背中追いかけてた
    眩しいとか悔しいとか
    言うより言わせたい
    
[/code]

I think the first sentence can be translated to "I chased after your back",
second one "Whether it’s too dazzling or it’s regrettable" the third one is
the one that I kind of do not understand. "言う" as I understand it is to say.
"より" is more than and I know たい refers to a strong desire/want. Hence, the
third sentence is " I want to say out more than what I want to say out?" which
sounds wrong. What is the difference between 言う vs 言わせたい?

P.S. Just started learning basic Japanese only.




Welcome do Japanese Stack Exchange! First, you are correct about 言う, より and
～たい meanings, but you are missing the
[causative](https://jlptsensei.com/learn-japanese-
grammar/%E3%81%95%E3%81%9B%E3%82%8B-saseru-causative-form-meaning/) form ～させる  
言う : to say  
～せる : make someone do "～" / allow someone do "～"  
～たい : want to "～"

Thus:  
言わせる : make someone say / allow someone say  
言わせたい : want to make say

So I would translate:

> 言うより言わせたい

as:  
_More importantly than saying, I want to make you say._  
or  
_I want to make you say it instead of saying it myself_
