I've not heard the radio edit yet, but got the Cahill, Wideboys, and (quite aptly named) Frisco remixes today.
It's a hugely catchy song, very suitable for the summer. The melodies are pure pop, in the same vein as the latest Katy Perry album. The Cahill mix is quite Kylie-esque, the Wideboys turn it into a more electrohouse track, and the Frisco mix sounds like first album era Cascada.
Although it's difficult to judge how big a hit it could potentially be until the all important radio edit surfaces.
Yeah the radio edits are coming soon, but this remix appeared today. I heard another one is out but I couldn't locate it.
Anyway, I like this one a lot. It also appears to be a radio rip, so the remixes aren't even being sold on itunes or anything yet.
