ASAAC (Any Song At Any Card) by John O’Toole

They load an unknown song on their phone. They then randomly select any card (Free choice). When the song is played on their phone, it’s all about one card. Incredibly the song’s card matches the selected card. No forcing. Any card can be named, even the Joker. You don’t touch their phone. No
