Thanks to a new application by a Seattle mobile-media company, iPhone users can channel donations to the Salvation Army by listening to Christmas tunes.

The application, created by the company Melodeo, streams hundreds of holiday songs by singers such as Nat King Cole, Bing Crosby, and by a Salvation Army brass band.

The application costs $2.99, of which $1 goes to the Salvation Army.

“The Salvation Army is excited to spread the good cheer of the season through music while offering a new way for our supporters to contribute to one of their favorite causes,” said Major George Hood, national community relations secretary for the Salvation Army, in a press release. “This is one music download that can make a real difference in people’s lives.”

How useful do you think iPhone applications will be in raising money?
