Most years, a record emerges that becomes the defining 'Ibiza anthem' of the summer. We've been struggling to identify these over the last couple of years. In 2008 the only track Addicted came home humming was the In Petto remix of Toca's Miracle – and that record is over nine years old. But this year there are two tracks which we think could define summer 2009. They're already in the iTunes dance chart, take a listen and let us know what you think.

Calvin-harris I'm Not Alone – Calvin Harris

Mylo's former protégé releases his first piece of new material since Dance Wiv Me, last year's collaboration with Dizzee Rascal that topped the charts for most of summer. I'm Not Alone is a very different beast. The chords are quintessentially Balearic and reminiscent of classics such as Out of the Blue by System F. We challenge you to keep this tune out of your head and your hands out of the air. The mixes by deadmau5 and Tiesto are worth checking out too.

Deadmau5 I Remember – deadmau5 and Kaskade

Canadian deadmau5 has been huge on the underground scene for the last couple of years, but this could be his breakthrough tune. The seductive vocals and beat make it equally at home in a club or on a chill-out compilation, and it's the sort of record that begs sea, sun, sand and a really good cocktail.
