Need research for music distributors

Partner/Get Music for a video editing application being built Hi There, I'm Serena and I am the community manager representing Playlog, an innovative app that is both a video editor as well as a social network platform: helps creators, edit and share their content and posting on a social media platform. We would love to get music/audio/sound into our app, so I was wondering if you could do some research on what the best company/distributor is. Please let me know if you could provide some information on distribution. I can send you the google sheets as well, to fill out. Thank you! Serena
