I have four albums by Anita Baker: the others being Rapture, Giving You The Best That I Got and Compositions.
Her first album, Rapture, is easily her best with neither of the following two coming near that very high standard. Don't get me wrong, they weren't bad albums, but Rapture was something extra special.
The fourth album. Rhythm of Love, comes closest to emulating Rapture without actually succeeding.
Anita's voice and her singing are excellent and are what makes her the supreme artist that she is and on Rhythm of Love the quality of the songs is nearly up to Rapture's standard. The songs are, however, not as catchy as on the first album and that is the biggest difference between them.
However, for me, Rhythm of Love is an improvement on "Giving You..." and "Compositions"; the songs are stronger and more accessible.
