The deal with APM Music, a joint venture of EMI Music Publishing and BMG Music Publishing, creates the largest and most diverse mashup music library available today, Fliptrack said.

Fliptrack.com was launched less than two months ago but over a half million visitors have already visited the site and created tens of thousands of slideshows, making the company a frontrunner in the music slideshow arena.

Thanks to the agreement, as well as APM’s large catalog of rock, classical, blues, folk, family, spiritual and holiday music, tracks from up and coming indie-bands from artists on Indie911 – an online social network, artist service provider and music store – can also be accessed.

In addition, APM and video game publisher Electronic Arts recently teamed up to make available the scores from many top-selling EA video games, including The Sims, the Medal of Honor franchise, and The Lord of the Rings series.

As the leader in production music, APM Music is a fantastic resource for Fliptrack’s community of half a million users looking to legally create great music videos and slideshows from their visual content, said APM president Adam Taylor. With APM, Fliptrack now offers the most comprehensive legal, music library available, giving users more variety and the very best mashup experience.
