Код для его обработки использую:

public class MainActivity extends AppCompatActivity {
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = findViewById(R.id.music);
        getResponse();
    }
    private void getResponse(){
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(ApiInterface.JSONURL)
                .addConverterFactory(ScalarsConverterFactory.create())
                .build();
        ApiInterface api = retrofit.create(ApiInterface.class);
        Call<String> call = api.getString();
        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {
                Log.i("Responsestring", response.body().toString());
                if (response.isSuccessful()) {
                    if (response.body() !=null) {
                        Log.i("onSuccess", response.body().toString());
                        String jsonresponse = response.body().toString();
                        writeMusic (jsonresponse);
                    } else {
                        Log.i("OnEmptyResponse", "Returned empty response");
                    }
                }
            }
            @Override
            public void onFailure(Call<String> call, Throwable t) {
            }
        });
    }
    private void writeMusic (String response) {
        try {
            JSONObject obj = new JSONObject(response);
            ArrayList<MusicModel> musicModelArrayList = new ArrayList<>();
            JSONArray dataArray = obj.getJSONArray(response);
            for (int i = 0; i<dataArray.length(); i++) {
                MusicModel musicModel = new MusicModel();
                JSONObject dataobj = dataArray.getJSONObject(i);
                musicModel.setArtistName(dataobj.getString("artistName"));
                musicModel.setTrackName(dataobj.getString("trackName"));
                musicModelArrayList.add(musicModel);
            }

            for (int j = 0; j < musicModelArrayList.size();j++){
                textView.setText(textView.getText()+musicModelArrayList.get(j).getArtistName()+ " " +musicModelArrayList.get(j).getTrackName());
            }
        }
        catch (JSONException e) {
            e.printStackTrace();
        }
    }
}

Возможно, мыслю в правильном направлении - указал в строке в скобках значение "response": JSONArray dataArray = obj.getJSONArray(response);

Верно ли это?
