She rarely/never had flop songs. But Soul Kiss was one of those. The lead song from her mid 80s album only reached #20 in the States.
However its one my favorites along with Deeper Than The Night. Those songs are not what you think about but they are great.
This video was shot cleverly because she was very pregnant during the shoot so they only film her laying down to hide it.
