Starting today, SoundCloud will let you share songs from its app directly to Instagram Stories, the company announced in a blog post.

To post a SoundCloud track to Instagram Stories, navigate to the song you want to share in the SoundCloud app, then tap the share icon at the bottom of the screen. Depending on the phone you’re using, you’ll either select the Instagram icon or tap “Share to Instagram Stories.” It will then open in Instagram Stories, with the album art as the background, and a movable sticker that’s also a link with the SoundCloud logo and name of the song.
