T-Mobile International, the European wireless carrier, has embarked on a creative campaign to coincide with its relaunched Mobile Jukebox.

The new à la carte service allows subscribers to download to both Windows-operated PCs and mobile handsets for just £1 ($2.02).

It kicks off in the United Kingdom, followed by Austria and Germany later this year, says Luke Magnuson, T-Mobile's music category manager. The service is powered by France-based Musiwave.

The offering, which features 500,000 songs from the four majors and local indies, is also being considered for T-Mobile Eastern European markets, such as Hungary, Slovakia and Poland.

T-Mobile already operates a full-download service in the Czech Republic, where it is powered by sister company Musicload.de.

"The new look of our Mobile Jukebox is now very simple," adds Magnuson. "You can buy a track from the front page with just two clicks, which you couldn't do before. It is also much more dynamic, being updated frequently."

The technology also features a song-recognition software developed with handset-manufacturer Sony Ericsson that allows users to point the device to a song being played and make an immediate purchase.

Additionally, its music locker stores tracks, enabling subscribers to retain their purchases even if they change mobile handsets. The locker also allows users to download and transfer songs to other devices.

To promote these new developments, T-Mobile has installed five "interactive bus shelters" in the shape of a mobile phone. The shelters can be found in central London's New Oxford Street and Tottenham Court Road; in Eden Street, Kingston-upon-Thames; at Piccadilly Station, Manchester in north England; and at Renfrew Street, in Glasgow, Scotland.

Each shelter features a touch-screen display that enables passers-by to plug in their headphones and to select to play any of 10 songs by hit artists.

Among the tracks available are "Tears Dry On Their Own," by Amy Winehouse; "Mer du Japon," from Air; Natasha Bedingfield's "Soulmate," and "Big Girl (You Are Beautiful)" by Mika.

The "bus-shelter" campaign ends July 16.
