Download a file reading first a file which contains the url - arrays

Question

I have an mp3.txt file which contains URLs to download. How do I read the contents to then download the URLs? I tried this but it's not working:
Func _downloader($link)
Local $dwnarrayread[3] = [IniRead(#ScriptDir & "\mp3.txt", "file_links", "link_1", Default), IniRead(#ScriptDir & "\mp3-2.txt", "file_links", "link_2", Default), IniRead(#ScriptDir & "\mp3-3.txt", "file_links", "link_3", Default)]
$dwnlink = InetGet($dwnarrayread[$link], #ScriptDir & "PSU-04.mp3", 1, 1)
Do
Sleep(50)
$prc = Round(InetGetInfo($dwnlink, 0) / (InetGetInfo($dwnlink, 1)) * 100)
GUICtrlSetData($progressbar1, $prc)
Until InetGetInfo($dwnlink, $INET_DOWNLOADCOMPLETE)
EndFunc
mp3.txt file :
[files_links]
link_1=https://ftp.psu.ac.th/pub/demo/mp3/PSU-04.mp3
link_2=http://somesite.com/files/file2.zip
link_3=http://somesite.com/files/file3.zip

How do I read the contents to then download the URLs?
Example (as per additional requirement):
_Download('mp3.txt', 'files_links', #DesktopDir & '\')
Func _Download(Const $sFileIni, Const $sSection, Const $sDest)
Local Const $aFile = IniReadSection($sFileIni, $sSection)
For $i1 = 1 To $aFile[0][0]
InetGet($aFile[$i1][1], $sDest & StringTrimLeft($aFile[$i1][1], StringInStr($aFile[$i1][1], '/', 0, -1)))
Next
EndFunc
Example as per GUICtrlSetData() -attempt:
#include <AutoItConstants.au3>
#include <InetConstants.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
_Download('mp3.txt', 'files_links', #DesktopDir & '\')
Func _Download(Const $sFileIni, Const $sSection, Const $sDest)
Local Const $aFile = IniReadSection($sFileIni, $sSection)
Local $aDownload[$aFile[0][0] + 1]
$aDownload[0] = $aFile[0][0]
For $i1 = 1 To $aFile[0][0]
$aDownload[$i1] = InetGet($aFile[$i1][1], $sDest & StringTrimLeft($aFile[$i1][1], StringInStr($aFile[$i1][1], '/', 0, -1)), $INET_FORCERELOAD, $INET_DOWNLOADBACKGROUND)
Next
Local Const $iWidth = 400, _
$iHeight = 20
Local $hWnd = GUICreate(#ScriptName, $iWidth, $iHeight * $aDownload[0])
Local $aHnd[$aDownload[0] + 1]
For $i1 = 1 To $aDownload[0]
$aHnd[$i1] = GUICtrlCreateProgress(0, ($i1 - 1) * $iHeight, $iWidth, $iHeight)
GUICtrlSetTip($aHnd[$i1], $aFile[$i1][1])
Next
GUISetState(#SW_SHOW, $hWnd)
Local $aInfo
While Not (GUIGetMsg() = $GUI_EVENT_CLOSE)
For $i1 = 1 To $aDownload[0]
$aInfo = InetGetInfo($aDownload[$i1])
GUICtrlSetData($aHnd[$i1], ($aInfo[$INET_DOWNLOADCOMPLETE] Or $aInfo[$INET_DOWNLOADSUCCESS]) ? 100 : $aInfo[$INET_DOWNLOADSIZE] / $aInfo[$INET_DOWNLOADREAD])
Next
If InetGetInfo() Then ContinueLoop
MsgBox($MB_OK, #ScriptName, 'No more running downloads.', 0, $hWnd)
ExitLoop
WEnd
For $i1 = 1 To $aDownload[0]
InetClose($aDownload[$i1])
Next
EndFunc
