I found a "personality quiz" that talks about ringtone types and what it says about you.

Here are the results:

Animal Sound, weird theme or other Sound Effect: You'll always have a bit of "kid" inside you. You are confident, diligent and like to live on the edge. You have a creative energy but also tend to be a bit disorganized.

An 80's or 90's song: You can sometimes be spontaneous and still do a little "air guitar" or "the robot", but mostly you are responsible and reserved. You do have a tendency to be loyal and resourceful.

A Current hit song: You like to be stylish and up on the latest trends but might secretly be a little shy or have low self-confidence. But you can turn on the charisma when you need to.

You, yourself or your kids: You tend to be social, understanding and reliable. You are a nurterer and sensitive.

Standard preset ringtone: You are dependable, comfortable in your own skin and laid back. You are way too busy to be concerned with what the latest trends are. You make friends easily and blend right in!
