Intro Options Unlisted Video

So people can help me pick which option sounds best for the intro I provided the video and the first bits of voiceover after the intro finishes so that the transition can be judged, but I didn't let to go on too far into the content.

The options are:

Option 0 - SoundFX Only, no music.

Option 1 - Round and Round We Go

Option 2 - Sine 00

Option 3 - Don't Get It

Option 4 - The Computer is Thinking
