Dare deshou ka?
 

Here's a very cute video of Nakashima Mika (中島美嘉) moving to a new apartment. There is a song playing in the background here @ 5:53. Can anyone ID this song/artist? The time stamp says July-30-2002, so I'm assuming it's something current to that date. It doesn't seem to be hers, as I've checked thru all of her albums and singles. It could be a collab with another group maybe? Anyway, I've been trying to figure this out for nearly two years thru various forums...
