Numb3r5! The Green Monkey Mix

I'm in the mix for the Green Monkey Music Project (thought it may not be official yet). There is only one rule for this mix, and it is very simple.All the selections must have a number of some sort in the title. There can be an actual number in the title, or the number can be spelled out (i.e. "Two"). I'll even allow adjectives like "Seventh".

• Four Minutes to Save the World, by Justin Timberlake/Madonna
• 500 Miles, the Proclaimers
• 1999, Prince
• 99 Red Balloons, Nena
• Just the Two of Us, Bill Withers & Grover Washington Jr
• Gimme Three Steps - Lynard Skynard

I'll post explanations soon...
