Swedish/Australian synth-pop duo Say Lou Lou has done it again!

The twins have delivered yet another electrifying pop anthem about the ups and downs of love, but the refrain in “Nothing But A Heartbeat” may be their most addictive offering yet.

“There’s nothing left inside of me. Ohh-ahhh, nothing but a heartbeat,” they sing in the light and airy hook. It’s hard not to bounce along to the song as the ladies sing on top of guitar licks, sweeping synths and drums.

“Nothing But A Heartbeat” will be available on iTunes on Feb. 9.

Say Lou Lou is supposed to release their full-length album Lucid Dreaming in February in Sweden, but a U.S. release date has not been confirmed. 2014 saw them teasing fans with satisfying songs such as “Everything We Touch” and “Games For Girls,” along with covers such as Daft Punk’s “Instant Crush.”
