now im no python expert but i think my issue derives directly from the fact it does not use English characters, im going to work to resolve this myself but keep this in mind if you ever come and update it again.

The script is downloading mp3 and mp4 from the same video and it is not downloading all the videos in the playlist

Hi!

I made significant improvements to your project. Let me push/open PR!

I'm working on a google colab of this, but I don't know what libraries to use because I used the ones metioned in the first few lines and it only found 1 library (pytube).

this is the issue i get now

i am entering a valid path for the music to be sent to, and my playlist should be valid

Hey!! Great script, really useful I was wondering if I can fork this repository for the purpose of adding a UI and a few new features do you mind??

PS: I'm opening an issue because I don't think Github has a way to directly send a message and I don't know how to contact you otherwise.

I changed line 24 from -3 to -4 and worked.

new_filename = default_filename[0:-4] + "mp3"

requirements.txt = pytube==12.1.0

latest version according to github = v11.0.1

?
