Getting TypeError: list indices must be integers or slices not str

To solve the issue Im doing like below, verifying if the body is not empty, but its not working it appears the same issue.

def song_lyric(song_name,artist_name):
    while True:
        querystring = apiurl_musixmatch + "matcher.lyrics.get?q_track=" + urllib.parse.quote(song_name) + "&q_artist=" + urllib.parse.quote(artist_name) +"&apikey=" + apikey_musixmatch + "&format=json&f_has_lyrics=1"
        #matcher.lyrics.get?q_track=sexy%20and%20i%20know%20it&q_artist=lmfao
        request = urllib.request.Request(querystring)
        #request.add_header("Authorization", "Bearer " + client_access_token)
        request.add_header("User-Agent", "curl/7.9.8 (i686-pc-linux-gnu) libcurl 7.9.8 (OpenSSL 0.9.6b) (ipv6 enabled)") #Must include user agent of some sort, otherwise 403 returned
        while True:
            try:
                response = urllib.request.urlopen(request, timeout=4) #timeout set to 4 seconds; automatically retries if times out
                raw = response.read()
                #print(raw)
            except socket.timeout:
                print("Timeout raised and caught")
                continue
            break
        json_obj = json.loads(raw.decode('utf-8'))
        if json_obj["message"]["body"] != "": # verifying if body is empty
            print(json_obj)
            body = json_obj["message"]["body"]["lyrics"]["lyrics_body"]
            copyright = json_obj["message"]["body"]["lyrics"]["lyrics_copyright"]
            tracking_url = json_obj["message"]["body"]["lyrics"]["html_tracking_url"]
            if(tracking_url!= ""):
                #print(body) #this print blank
                #print(tracking_url)
                lyrics_tracking(tracking_url)
                return (body + "\n\n" +copyright)
            else:
                return "None"
        else:
            return "None"

Also when there is no track the response is:

{'message': {'header': {'status_code': 404, 'execute_time': 0.0011160373687744}, 'body': []}}

Thanks! It worked with "if json_obj["message"]["body"] != [].
