ad with woman singing in train station

[drgonzo8]

It might be a long shot anyone knowing this but i will ask anyway. A couple of years ago there was an advert where a woman sang along to the song that was playing on her walkman. I think it was for a mobile phone company but cant be sure. Anyone know what it was? I know this is a bit vague but it is doing my head in!

I think it was an ad for the Nokia 3300 - the lady was listening to a song playing on the phone (it plays MP3's) and people thought she was busking and were giving her money. Is that the ad? Or did you want to know the song?

If you want to know the music it was The Space Between by the Dave Matthews Band
