H&M What's the name of this song?

I heard it in H&M yesterday, but I haven't been able to find the song title.
The song was sung by a guy, and it had the lyrics "We're gonna go to the beach....with all my friends". Thanx!
*It's not West Indian Girl-All My Friends

I also work in H&M, but I tend to forget which songs they are playing :/
I remember these, though:

Annie - I Know Ur Girlfriend Hates Me
Leona Naess - Blue Eyed Baby + Charm Attack
Sara Bareilles - Love Song + City + Fairytale + Love On The Rocks
Jason Mraz - I'm Yours + Geek In The Pink + Make It Mine
Jack Johnson - Sitting, Waiting, Wishing + If I Had Eyes + Never Know + Sleep Through The Static
Alphabeat - 10,000 Nights Of Thunder
Sia - The Girl You Lost To Cocaine + Day Too Soon
Junior Senior - Shake Your Coconuts
The Killers - Read My Mind + Somebody Told Me + Human + Spaceman + The World We Live In + I Can't Stay
The Bird And The Bee - Again And Again + How Deep Is Your Love
Duffy - Rockferry + Warwick Avenue + Serious + Stepping Stone + Rain On Your Parade
The View - Claudia
