+    Overview:
+        Nicole is a program that searches for lyrics and writes them into the mp3-tag "USLT".
+        There is a 5 second delay between each request to azlyrics.com because the site will block your ip if there are too many requests.
+    History:
+        Nicole can create a history of all files that were processed in ~/.configs/nicole.
+        If a file is in the history, it will be skipped unless ignore_history=True.
+        If the lyrics for a file can not be obtained, it is added to ~/.configs/nicole/failed_files.
+        Those files are not skipped, the file only exists so that you can see which lyrics were not downloaded.
+    azlyrics:
+        Nicole creates a azlyrics url from the title and artist mp3-tags of the file.
+        The lyrics are extracted from the html document using regex.
