In August, Instagram significantly expanded its music and collaboration features 2023: users could for the first time add music to photo carousels, publish Collab Posts together with up to three additional accounts, and start new Reels challenges via the Add Yours sticker.

These features may seem 2026 less spectacular than they did back then, but they remain part of an important trend: Instagram increasingly treats posts as shared, remixable content objects rather than isolated publications from a single account.

Music for Photo Carousels

Instagram had already used music in Stories, Reels and individual feed photos. 2023 the option was added to also accompany photo carousels with a song.

This allows, for example:

  • Event recaps,
  • Product dumps,
  • Moodboards,
  • Travel or behind-the-scenes carousels

to be given a continuous soundtrack.

For brands, this is especially interesting when a carousel is deliberately structured like a small storyboard.

Collab Posts with Multiple Accounts

At the same time, Instagram expanded Collabs.

Instead of just one additional co-author, up to three friends or partners could be invited to publish a feed post, carousel or Reel together.

Once accepted, the content appears on the profiles of the participating accounts and can reach their respective audiences.

That this mechanism remains strategically relevant years later is shown by the current Emplifi analysis of Instagram Collab Posts: creator-led collaborations showed the strongest performance uplift there. The study is not proof of causation, but it underlines the value of genuine shared distribution.

Add Yours brings community content into the same workflow

With the Add Yours sticker, creators were also able to start prompts and challenges that followers respond to with their own Reels.

This turns a single post into a small content thread: the creator sets the impulse, and the community produces variations.

Instagram later expanded this principle in Stories with Add Yours Templates. Srocket has a separate, updated guide on this.

What does this mean for brands?

The three features share a common denominator:

A post no longer has to work only from the brand's own account.

Brands can combine music, shared authors and community responses to spread a launch or campaign across several profiles.

This is especially useful for:

  • Creator collaborations,
  • Co-branded products,
  • Events,
  • Music and entertainment campaigns,
  • UGC activations.

How brands use Instagram 2026 more systematically is shown in our current Instagram marketing guide for businesses. For professional creator collaborations, Meta's Creator Marketing Hub is also relevant.

Conclusion

The music and collab features 2023 introduced are no longer exotic novelties today.

But they were an early step toward the Instagram we 2026 see: more shared distribution, more remixability and more connection between creator, brand and community content.
