"Mirrors" is the second song to precede Justin Timberlake's third solo album. Its most noticeable feature is its eight-minute length. The singer mentioned classic rock acts, rather than contemporaries -- such as Frank Ocean's "Pyramids" and the-Dream's flowing suites -- as his inspirations, yet this is less an epic than a drawn-out midtempo pop ballad. It could fade out or end abruptly around the four-minute mark, but it takes another four minutes to dissolve. Over Timbaland's clumpy beat (with beatboxing) and grand strings, Timberlake pleads with heartfelt devotion, but it's not one of his more remarkable singles.
