15-16-17's sound ranges from fun, and youthful -- sort of like an earlier version of Musical Youth -- on "Girls Imagination" (a clever remake of The Temptations' "Just My Imagination" from the girl's point of view), "I've Been Watching You," and their take on The Supremes' "Baby Love" to a sultriness that exceeds their ages on "Someone Special," the ethereal "The Weather," and a lovely cover of The Bee Gees' "Emotions".
For the uninitiated, Lovers Rock sounds like a Philly Soul ballad played over a fat reggae bassline, it usually has a soulful kind of intro, not just a straight riddim like "rub-a-dub". Also as a generalization, the majority if not all Lovers releases come out of the UK, for reasons that I am not clear on, Lovers just never took hold in JA or NYC.
Here are videos of two of the songs on Magic Touch:

9-I've Been Watching You
