EXAMPLE DICTIONARIES:
Analyzing Song Lyrics in 3 steps:
+ Create a dictionary that  counts the amount of times a word shows up in the lyrics of a song
+ Create a function that finds the most common word and tells us how many times it occured
+ Create a function that collects all the words that appear at least X times in the song
