Short answer: not from Flomixy - and it isn't a missing Flomixy feature. Instagram doesn't allow it for any scheduling tool.
Why music isn't available
Instagram's music library - trending sounds and licensed tracks - lives inside the Instagram app only. When a scheduling tool publishes a post or Reel through Instagram's official publishing tools, Instagram does not allow attaching a track from that library. This is a licensing rule Meta applies to every third-party app, so no scheduler (Flomixy included) can add catalog music for you.
How to post with music anyway
You have two good options:
- Add the audio to your video before you upload it. Any music that is already part of the video file - added in your editing app - publishes normally through Flomixy. It shows up as original audio on the Reel. Just make sure you have the rights to use the track.
- Publish that specific Reel from the Instagram app. If you need a track straight from Instagram's music library for one particular Reel, create and post it directly in the Instagram app instead of scheduling it through Flomixy.
Good to know
- This applies to Reels and video - that's where Instagram music lives. Image and carousel posts don't carry music at all.
- Your own recorded sound, voice-over, or licensed music baked into the file always publishes fine.
