It changes ALL the time...
My two summer anthems for 2015 have been:
Pray to God - Calvin Harris, and "Five More Hours" - Deorro & Chris Brown
Lately, this has been in heavy rotation--the wife loves it:
Reality - Lost Frequencies
To get things hoppin' I've been enjoying The Hum - Dimitri Vegas & Like Mike, Toca - Carnage, Lift off - W&W.
To get things going with a little twist:
A l'italienne - Les Jumo, and Danza Kuduro - Don Omar.
The Wife has been loving to surf to "A Little Party Never Killed Nobody" - Fergie.
And it seems like when it's time to head back to the dock this one almost always gets played, "The Veldt" - Deadmau5
Music is integral to our boating experience. I have a variety of playlists for different scenarios.
