UK upstart Anne-Marie dropped this single in May 2016, along with press release that read:

‘Alarm’ is about somebody I was dating and I guess I just always had a suspicion that he was doing something naughty. I’m a bit of an investigator and I found out my inkling was right! The thing is, he left someone to be with me and I always thought he could do it again. I love this song so much and I hope you love it too!

Production was handled by Steve Mac with assistance from Amir Amor, who is part of the UK drum and bass band Rudimental. Anne-Marie was the vocalist that toured with Rudimental for two years, and also signed to their label, Major Tom. Steve Mac (and writing partners Wayne Hector and Ina Wroldsen) are the pop confection-half of this song. They’ve worked with major acts like Britney Spears, One Direction, and Nicki Minaj.
