Why the file is not downloaded in full with this script?

Is there any .mp3 on that terrible "illegal" site that work

Back to Python,this is how you download.

import requests

url = 'http://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_700KB.mp3'
with open('sample.mp3', 'wb') as f:
    f.write(requests.get(url).content)

Get file name from url.

import requests
import os

url = 'http://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_700KB.mp3'
file_name = os.path.basename(url)
with open(file_name, 'wb') as f:
    f.write(requests.get(url).content)
