There was a video on MTV2 that was completely animated and it pictured
a young woman walking, riding a bus through some metropolitan area,
similar to NYC.  The only lyrics I remember are "When I'm weak, I find
strength in you. And I when I'm lost you know how to change my mood. 
And when I'm down you breathe life all over me..."  Okay that's all I
remember.

Hi Cece2005,

The song you are looking for appears to be Destiny by Zero 7. The song
appears on the album ?Simple Things? and is also featured on the
official soundtrack for Blue Crush.

The lyrics you refer to are: 
?When I'm weak I draw strength from you 
And when you're lost I know how to change your mood 
And when I'm down you breathe life over me 
Even though we're miles apart we are each other's destiny?

entertainment section, in an artist spotlight on Zero 7.
