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

[ODIS]

Well, the error is appearing because if you're trying to get non-existing lyrics, you get response with another data structure. So it will fail here:

json_obj = json.loads(raw.decode('utf-8'))
body = json_obj["message"]["body"]["lyrics"]["lyrics_body"]

Try to put there a breaking point and debug it. You'll see it clearly.
