Why Audio Matters for Instagram Growth

The Viral Power of Trendy Audio

Instagram's algorithm favors Reels using trending audio - tracks featured in the Instagram music library get 53% more reach (Social Media Today, 2025). But what if you've already posted with the wrong sound?

Here's how to fix it:

  1. Open Instagram and go to your profile
  2. Select the Reel and tap the three-dot menu
  3. Choose "Edit" → "Audio" and select a new track

Pro Tip: Use Fansoso's audio trend tracker to discover viral sounds before posting.
