This song is already a mega-smash internationally—58 million views plus—but hasn't really seen much rotation in the United States. Much as Robin Schulz transformed Mr. Probz's "Waves" into a supermarket mega-hit last year, German producer Felix Jaehn's four-on-the-floor-plus-trumpet remix of Omi's 2012 reggae hit "Cheerleader" looks like this summer's massive wedding singalong. Either embrace it, or get ready for a rough couple of months! Actually, it's hard to imagine anyone being anything more than mildly bemused by its generally cheery vibe: effervescent by design.
