Thanks for your contribution and sorry for replying too late.

I had to delete your manual "404" return. To recap my changes, whenever the "getLyrics" or "getSongs" is called and the status code is not "200", then my code looks to see if the user specified a search engine.
-> If they did not, then it sets the search engine to Google and recurses, and resets itself back to self.search_engine='' after it returns. If
-> If the user DID specific a search engine (which also covers the case above where the function automatically recurses), then it returns the ACTUAL status code of the request instead of the hard-coded 404 error. This gives more accurate information for the cause of the issue whenever a look up fails.
