Acording to songofthesalesman.co.uk the latest T mobile is Bedouin Soundclash, When the night feels my song. Not sure if it's the foding building ad, but you can hear it on that site.
it is definately bedouin soundclash,
and the track 'when the night feels my song' is off their second album 'sounding a mosaic', which i recommend.
Emerging from Canada, they are already making a scene, and i wish them all the success coz they deserve it
