# Incorporates tuples, lists and disctionaries - all in a single use case



"""
Create a program to analyse song lyrics with the followinng three features/functions:
    - a frequency dictionary that maps strings to integers; Return type is a dictionary, format {word;frequency}
    - word(s) that appears most often. Return type is a tuple,  format (list, int) for ([List of most freq. occoring word(s)],frequency)
    - words that appear at-least x number of times (x - user input); Return type is a list of tuples, each tuple has format (word,freq)
    
Comment: Not entirely straightforward, but will get the job done

Happy to have written efficient code
