Electro-pop outfit Candy Collection returns with a brief but affirming set of songs on the 4 Plug-in Songs EP. This style of pop — criss-crossing synths, bouncy drum machine beats, a copious amount of digital filter for the vocals — has been popular to varying degrees over the past decade, and while Candy Collection are simply a continuation rather than any jump forward for those familiar sounds, they do it well.
