So I'm looking for this song by an indie-pop band that was released 3-4 years ago (at the time where a bunch of indie started playing on the radio).

I don't remember any of the lyrics but it's very energetic song by an indie-pop band from North America (Most likely USA). I can't remember the name of this band but I think that this was their only hit song. The song didn't made the Billboard 100 but it probably had a decent impact on rock charts.

The thing I remember the most is the music video where people were playing and swimming in the sea.

Additional details
-Leader singer is a guy
-It's not a song by Bastille, Walk of the Earth, Foster the People nor Off monsters and men

My wild guess is from 1994, "Santa Monica" by Everclear (not an Indie song)

"We can live beside the ocean. Leave the fire behind.
Swim out past the breakers. Watch the world die."

Ambrose - Oceanside ?

Thanks guys for the help but I was finally able to find it by myself.

It's Youngblood Hawke - We Come Running

Out of nowhere, the words "we" and "running" came across my mind and it was enough information to find what I was looking for.
