[SOLVED] Need help downloading spotify playlists efficiently using SpotDL

[SOLVED] Solution: https://lemmy.ml/comment/4317564

edit: Why are you booing me? This is c/piracy

I am doing all of this using ChatGPT, I know enough bash to understand the script partially, but not enough to write the script myself.

I recently posted bash script(click) to download songs on spotify using Spotdl Updated Post

This is all good, but I am not trying to download whole playlists and I want to make sure to

1. Not download any songs multiple times by comparing the files you are trying to download with the songs you have downloaded already.
2. Add the songs' URL to the Archieve_file so it doesn't download it again. i.e., compare and if present, exit loop, if not present in file, download and add link to the file.

This was easier when I was dealing with only song links and not playlist links. But now, playlists complicates the equation, but if I can achieve this, I can basically add this script to crontab and make sure I always have a local copy of the songs in my playlist and these playlists would be checked regularly for new downloads and new songs would be downloaded. This is really cool!

Now, the complications I am facing, I don't know how to get the URLs of the spotify songs out of spotify playlists using spotdl or any cli package. If I can do this then, I can make the script go through each link clean the link of unncessary attributes and then download it or if it's downloaded already, move on to the next song.

Now, I don't know how to do it. It would be very helpful if you guys could share any scripts that you have which will achieve this effect or help me get the song URL's from a playlist using a cli package.
