You have to play around with the search to get what your after. Try searching for the main words of a song title(keywords), and not the full title. Try adding the name of the artist to the search(first name, last name, or both). Try using the different search catagories, all files, audio, video, ect.
Sometimes just for shitz and grins, I'll take a list of the top files(music) and go one by one using the method above, and I can get most if not all the files I'm after.
