Harley's In Hawaii
That minor 3rd arpeggiated acoustic riff had me hooked from the jump. Love the beat and that throaty bass-line pumps the tune along like a Twin Cam V-twin. I'm guessing Max Martin is the brains behind the production here, but it does evoke a Dr. Luke feel.
Thematically, this is one of Katy's strongest songs since something off the Prism album. I can't get enough of it, it has that Teenage Dream addiction quality. Her strongest work is when she plays the seductive roll.
Melodies are super fresh and engaging. Always changing and moving yet staying simple at the same time. Well crafted all the way. Makes me wanna ride Harley's in Hawaii.
