hello,
so i tried to fetch the stream URL for a video with id As_4JTmHuW4 and passed a signatureTimestamp derived from ytmusic.get_signatureTimestamp(ytmusic.get_basejs_url()) to get_song

the resulting streamign URLs however were invalid

this is the one-lines used for the get_song call

song = ytmusic.get_song(videoId='As_4JTmHuW4', signatureTimestamp=ytmusic.get_signatureTimestamp(ytmusic.get_basejs_url()))

this was the string found in the signatureCipher property of the resulting song's streamingData

if i'm not missing something, the url part is supposed to be a valid streaming url, please let me know if something's wrong

Unfortunately I don't know much about streaming URLs, tagging some people who might know more.

@addyett - Those streaming URLs still need to be de-obfuscated before using. You can try youtube-dl or pytube to do this.
I do something like

from pytube.cipher import Cipher
from urllib.parse import parse_qs

resp = requests.get(ytmusic.get_basejs_url())
PTC  = Cipher(js=resp.text)
# "sigCiph" var is the signatureCipher you got from get_song
sc = parse_qs(sigCiph)
sig = PTC.get_signature(ciphered_signature=sc["s"][0])
url = sc["url"][0] + "&sig=" + sig + "&ratebypass=yes"
# "url" variable should now be valid and ready to stream.
