Sony BMG has agreed to distribute music from games developed by Konami to various digital outlets, including iTunes, Rhapsody and mobile operators.

The deal is limited to original music created specifically for Konami games, and marks the first time these tracks will be available in digital form. Konami's music catalog includes 25 years worth of classic games such as Contra, Castlevania, Silent Hill, Dance Dance Revolution and more.

The move is the latest in a growing trend by videogame publishers to monetize their original scores, ever since the Mario Brothers theme song became a No.1 ringtone. Electronic Arts and Nettwerk Music Group just last year formed a record label called Artwerk, forged out of a similar digital distribution deal.

Sony BMG has been growing increasingly interested in the gaming space, acting as publisher for a number of mobile games that remain in various stages of development.
