Why can't a mystery alarm be public?

A public alarm can reach anyone, and nobody on it could see what it was before it rang. Keeping mysteries to friends alarms means everyone on one got the link from someone they know. For a release every fan can find, use a public drop alarm. See [ringing every fan when your track drops](/soundcloud-artist-drop-alarm).

What do fans see before it rings?

A curtain, your name, how many are waiting and what it's waiting for. With **Hide the trigger too?** on, they don't see when it rings or where its link goes either.

Do fans need SoundCloud?

No. The track plays in LFG Alarm, and a secret link opens in their browser.

Can I make one for my crew only?

Yes. Under **How people get in**, pick **I approve each one** and add people by username or email instead.

How to make a mystery drop for your fans

What a mystery alarm is

A mystery alarm hides what's inside until it rings. Fans who join see a curtain where the name, wallpaper, sound and your note would be. They can see that you made it and how many others are waiting. If you also switch on Hide the trigger too?, they don't know when or why it will ring, or where its link goes.

Mystery alarms are friends alarms, never public ones, so they don't show in Discover, where anyone can browse public alarms. That's what makes them right for your inner circle: you share the link where your real fans already are.

Two ways to make one

Ring when the track goes live. Make a drop alarm on your own SoundCloud profile, so it rings the moment your new track is public. Upload it as private first, and switch it to public, or schedule the release, when you're ready. Fans hear it the minute it's out, with Play the drop to play it right there.

Ring at a time you choose, with a secret link. Make a time alarm for your release moment. On SoundCloud, upload the track as private and copy its secret link from Share. Only people with that link can hear it. Paste it as the alarm's Call to action link, the link that opens when someone answers the ring, and switch on Hide the trigger too? so the link stays out of sight until then. When it rings, your fans tap through to an early listen nobody else has.

The link can be anything you like: the private track, a pre-save page, a merch drop, a ticket sale.

Set it up

Make the alarm, a drop alarm on your profile or a time alarm, and give it a look in the studio. Fans won't see it until it rings, so make the reveal worth it.
Turn on Make it social and pick Friends. Under How people get in, keep Anyone with the link rides, so any fan you send it to can join.
Switch on Keep it a surprise, and Hide the trigger too? if you want the time kept secret as well.
Write your Keeper's note, the message pinned on the alarm. On a mystery it stays behind the curtain too, so make it part of the reveal: "You were first. Thank you for waiting."
Copy the alarm's link and post it in your Discord, your close friends story or your mailing list, with your tease in the post itself: "Something I've been sitting on for a year. Tap this." The link looks like lfg.gm/a/<alarm-code>.

The surprise locks once fans join, so they always get the mystery they signed up for. You can still change a time alarm's time, and riders are told.

Make the reveal land

Post the link days ahead. The alarm can only ring phones that joined, and a growing count of who's waiting is something to post about.
Give it a time people can be there, like the evening, not 3am, unless 3am is the point.
Treat it as a surprise, not a vault. The curtain keeps the reveal for the ring, but a fan's phone holds the alarm so it can ring offline. If the early listen is for the inner circle only, use SoundCloud's Reset secret link once the track is public, so old copies stop working.

Ask your AI to set it up

If you use an AI app such as Claude or ChatGPT with the LFG Alarm connector, it can make the alarm and hand you the link.

Have your AI agent make it.

Paste this into ChatGPT, Claude, Grok or any AI agent that can add a connector, not into the LFG Alarm app. The setup steps come with it: get the LFG Alarm app, connect it to your agent once, and your agent makes the alarm in your account.

Make a mystery alarm for my fans for Friday at 8pm, friends only so anyone with the link can join, with this link when it rings: [your SoundCloud secret link]. Keep it a surprise, hide when it rings too, and give me the link to post in my Discord.

Already have the LFG Alarm app and connected it to your AI agent?

Why it works. It gives the time, who can join, the link to open and how much to hide, which is everything the alarm needs. Connect LFG Alarm to your AI app first: see [AI agents](/agents).
