Stream URL of soundcloud track where streamble is

There is a property "streamable" of a track which is if "false", I'm unable to get stream_url of that track.

But I see there are few downloaders which gets stream_url of the very same song & then gets then cdn link of that track.

I even did authenticate my app but no luck finding the stream_url. Here is what I did.

import soundcloud

# create client object with app credentials
client = soundcloud.Client(client_id='YOUR_CLIENT_ID',
                           client_secret='YOUR_CLIENT_SECRET',
                           redirect_uri='REDIRECT_URL')

# exchange authorization code for access token
code = params['code']
access_token = client.exchange_token(code)

#'YOUR_ACCESS_TOKEN' is access_token which I got in above step.
client = soundcloud.Client(access_token='YOUR_ACCESS_TOKEN')

track = client.get('/tracks/161730338')

Below is the track object

According to documentation I was supposed to get the stream_url from

# get the tracks streaming URL
stream_url = client.get(track.stream_url, allow_redirects=False)

# print the tracks stream URL
print stream_url.location

I'm stuck here from 4 days. Is there a way to get the final cdn link of the MP3 track or How do these soundclouddownlaoder do this.

If the stream_url key returns a null value, I've found that the streams endpoint will return a valid URL.

HTTP GET: https://api.soundcloud.com/tracks/[TRACK_ID]/streams?client_id=[YOUR_CLIENT_ID]

Disclaimer: This is an undocumented endpoint and is subject to change at anytime by SoundCloud.

HTTP GET: https://api.soundcloud.com/tracks/161730338/streams?client_id=[YOUR_CLIENT_ID]

The preview_mp3_128_url key-value pair has the 128kbps streaming mp3 you want.

If the preview_mp3_128_url is not the full track, you'll need to use a tool such as ffmpeg to download the HLS transport stream

ffmpeg -i "https://ec-hls-media.soundcloud.com/playlist/EDiPRlpWkJ2V.128.mp3/playlist.m3u8?f10880d39085a94a0418a7e062b03d52bbdc0e179b82bde1d76ce6ad1a416907458c1576abbf27bccb1984bf2890809c25cb2c95f826eba5858b2322a2cc08c48f3664ebef63724f43e9baa7d819586e497b7175430826823cbebd16" -c copy test.ts

That will give you the full mp3 file of the track.
