E-Girls are a 28-member-strong idol pop collective constructed by Avex. The "E" stands for "Exile," as in this is the female version of greased-up R&B doofs Exile.

The songwriters and producers making the songs on their second album, "Colorful Pop," boast backgrounds making mediocre tracks for Johnny's boy bands and various K-pop outfits. The album also follows on from a forgettable debut last year.

Despite every pitfall "Colorful Pop" faces, though, it inexplicably works out after pressing play. This is Japan's first great pop album of 2014 — "pop" being key — for listeners who have no problems with a crew of studio careerists steamrolling over imperfections in the pursuit of glistening digital thrills. However the careerists pull it off, turning a cheesy album title into an accurate depiction of what awaits the buyer.
