U.K. download store 7digital.com has signed a deal to integrate its 6 million-strong MP3 catalog into the Songbird media player.

Songbird users in the U.S. and Europe can now purchase and download tracks directly to the player and transfer to MTP-compatible portable devices

Users can click the 7digital.com music store link in Songbird to access the store and purchase tracks without leaving the application. Tracks are automatically downloaded into the user's Songbird library and 7digital.com makes recommendations based on recently played tracks on Songbird.

Songbird is an open-source, customizable desktop music player designed to help music fans use their music collections to find, discover and acquire new music. It is distributed free under the open-source GPL license.

The integrated service is available now at getsongbird.com and direct purchase of MP3s is available in the U.S., UK, Ireland, Germany, France, Spain, Austria, Italy, Belgium, Netherlands, Portugal and Switzerland.

Ben Drury, CEO of London-based 7digital.com, said in a statement: "7digital and Songbird is a killer combination for anyone who wants a dynamic, open music player. Songbird blows other media players away in terms of device support and extensibility and we're very excited to be partnering with them to allow users to buy, download and transfer MP3s onto a multitude of devices. The Songbird Platform made it quick and easy to integrate 7digital into Songbird."

Pricing will be based on geographical location and will correspond to the pricing on the local 7digital Web site. A portion of the revenue from 7digital sales will go towards further developing Songbird.

Ethan Bauman, director of business development at San Francisco-based Songbird, added: "320kbps MP3s are downloaded directly into a library that keeps fans abreast of local gigs and band news, as well as displaying live concert photos, artist bios and more. We're happy to have a way for our fans to buy and download high quality MP3s in the U.S. and Europe that supports artists and Songbird."
