Whether or not you subscribe to my theory that John Legend is actually Alicia Keys with her voice pitched down to a convincing masculine tenor, you can't deny the similarities. They're piano-based crooners, now and then produced with a hard-edged hiphop finish (in Legend's case that's thanks to producer pal Kanye West), and they're both gifted songwriters. As the title suggests, Legend's sophomore exercise in realistic love songs is consistent with his solid debut, Get Lifted. His formula - seductive words clad in mature, wistful tones - bubbles to a boil on Heaven, Stereo and gross couple anthem P.D.A. (We Just Don't Care). But once again, some soul listeners may find the product too pretty. Legend's lounge-track sentimentality often spills into schmaltzed-out Streisand-on-Broadway territory.
