mp3=True not resulting in error free file.

[KS-HTK]

Describe the bug Using yt.streams.get_audio_only().download(mp3=True) does not produce issue free mp3 file. The file can be played back but the id3 metadata is broken somehow. Neither eyed3 nor Windows explorer can add or modify the metadata of the downloaded file.

---

code that was used that resulted in the bug

import os
from pytubefix import YouTube
from pytubefix.exceptions import AgeRestrictedError
import eyed3

yt = YouTube("https://www.youtube.com/watch?v=dQw4w9WgXcQ")
yt.streams.get_audio_only().download(mp3=True, output_path="music", filename="test")
audpath = os.path.join("music", "test.mp3")
file = eyed3.load(audpath)
if file is None:
  print("Error Could not load audiofile")

---

Expected behavior eyed3 should be able to load the file as it should be an mp3 mime-type.

converting from downloaded mp4 to mp3 using moviepy and then using eyed3 to load works fine.

Desktop (please complete the following information):

• OS: Win 11 Pro 24H2
• Python Version [3.10.11]
• Pytubefix Version [8.3.2]

it is not corrupted, in fact it is not a real mp3

[JuanBindez]

so it returns None
