I made this video to show how it works:

This is the Windows batch script I had ChatGPT create for me:

@echo off
setlocal EnableDelayedExpansion

REM Check if the script is provided with a valid parameter
if "%1"=="" (
    echo Please provide a line number.
    exit /b 1
)

REM Check if the parameter is a positive integer
set "param=%1"
set /a "param=param+0" 2>nul
if not defined param (
    echo Invalid parameter. Please provide a valid positive integer.
    exit /b 1
)

REM Check if the parameter is within the valid range (greater than 0)
if %param% leq 0 (
    echo Invalid parameter. Please provide a valid positive integer.
    exit /b 1
)

REM Set the path to your text file containing the list of MP3 files
set "textFilePath=d:\playlist.m3u"

REM Check if the text file exists
if not exist "%textFilePath%" (
    echo Text file not found: %textFilePath%
    exit /b 1
)

REM Read the corresponding line from the text file
set "mp3File="
for /f "skip=%param% delims=" %%A in ('type "%textFilePath%"') do (
    set "mp3File=%%A"
    goto :PlayFile
)

REM If the parameter is greater than the number of lines in the file
echo Line number exceeds the number of lines in the file.
exit /b 1

:PlayFile
REM Play the selected MP3 file
echo Playing: %mp3File%
start "" "%mp3File%"

exit /b 0
