The MQR is a subjective rating for video game music I came up with a few hours ago. It goes something like this:

MQR #1: “What? I was humming the music from <game>? Oh, I’m sorry.”
MQR #2: “Of course I can hum a song from <game>. Which one would you like to hear?”
MQR #3: “The theme from <game>? It goes something like this…”
MQR #4: “Hey, that’s the theme from <game>!”
MQR #5: “Hm, that music sounds like something from <game>.”
MQR #6: “Hm, I know that song… I could swear I played a game with that music.”

Use at your own discretion.
