Strategy to for viral Sound - How to push my own Sound on TikTok ?

I made a short sound/song and started posting videos with it. I'm almost at 800K combined views on those 3-4 videos that use my sound.

But people don't seem to really engage with the sound itself. They watch the video, like, share, comment, but there's not much activity on the sound. It's a funny, quirky, catchy song. I had one post where I subtly urged people to use it, but I've only seen about 10-15 uses of it in stories, not actual posts.

What strategy would you suggest to grow my sound?
