I wrote code that chooses a random set of Chinese characters, asks the user what the characters are, and if they meet a certain criteria they level up (ex. get more than 50% correct). I want to know if there is a better way to have fewer lists, better organization, etc.

This script records audio from the computer's output and passes it to a C program that fingerprints it and queries the Gracenote database. If it identifies the audio then it offers options to look it up on Discogs. I made this because I wanted a way to identify tracks in DJ mixes that didn't invo...
