Not only does this song sound exactly like Sugar, We're Goin' Down instrumentally but it also has lyrics reminiscent of Green Day's Minority and an opening vocal part reminiscent of All Time Low's Me & You. Listen & tell me I'm wrong.
DNCE's song Cake by the Ocean (released September 18, 2015) bears a strong resemblance to several songs including Donna Summer's Bad Girls, Falco's/After The Fire's Der Kommissar, and particularly Cake's Never There (released October 13, 1998). DNCE's Joe Jonas has suggested that the title resulted from a mistranslation of "sex on the beach" by a Swedish producer (perhaps it's a thinly veiled referenced to the song's true lineage). Cake by the Ocean and Never There share the same key (E minor), basic verse chord progression (Emin-Amin-B7sus4-B7), and production/arrangement (single lead guitar riff outlining the chord changes).
