"nothing" doesn't quit on first input

[kbuffardi]

During the application, if the user enters nothing then it usually ends the program. However, there is a bug so that if they enter nothing on the very first input, it does the following:

What are you listening to?
nothing
Great! Let's listen to more
What's next?

And prompts the user to enter again. Instead, any time the user enters nothing, the program should terminate without any more interaction.
