Earworm is a music prediction effect for professional performers.
Here's what happens:
- You ask a friend to take out their phone, mute the volume and open YouTube.
- You then take your friend's phone and play a song, giving the phone back with its screen facing downwards.
- Now you apparently mentally transmit the thought-of song to your friend.
- Your friend names *any* song, turns the volume up on their phone and looks at the screen to hear and see that your prediction was correct... that exact song is playing on their phone!
The entire effect happens on their phone.
Earworm is built for real-world performance. It gives you multiple advanced input methods, flexible reveal options, and powerful integrations so you can adapt the routine to your style, language, and audience.
Everything can be inspected afterwards, with nothing suspicious to find.
Features include:
- Predict songs, music videos, trailers, or almost any searchable video
- Multiple input methods, including voice and covert browser input
- Performable in multiple languages
- No accomplice required

There are very few names in the Magic industry that when there name is attached to a product you know it’s going to be incredible. Marc Kerstein is one of those very few names. Earworm is no exception. Highly recommend.
Music mind reading - incredible

This app works perfectly. A real fooler. It's easy to learn and the support from Mark is great. I recommend this very highly. Five stars for sure. There is even the Facebook group for owners of this app, where you can share ideas with other magicians. How cool is that?
It really works

This app works as advertise and it has really freaked the people I have performed it for out. And what is even better is Marc, the creator, continues to enhance with user feedback. Love it.
