When it comes to songwriting, Cameron Montgomery focuses on basics, not borders. His earworm hooks and evocative lyrics perfectly complement the deep-twanging country riffs on Walker Hayes’ “That Dog’ll Hunt” and Justin Moore’s “Straight Outta The Country.” And they’re equally on display in Weird Genius & Violette Wautier’s ethereal, electronic “Future Ghost” and Hot Chelle Rae’s pop/R&B collision “Come My Way.”
