Social media music licensing firm Rumblefish launched a free SDK that allows iOS app developers to find and incorporate music into their social video or photo apps.

The Friendly Music SDK is built on the Rumblefish API and includes a music recommendation tool for finding suitable music for products from the Rumblefish Music catalogue, which has more than 750,000 tracks.

"After seeing millions of videos online use our music as soundtracks, we were compelled to build the mobile SDK and help developers bring soundtracks and other music-related features into their apps quickly and easily,” said Rumblefish founder and CEO Paul Anthony.
