Yes, this covers pretty much all her hits. However, this Anthology is nearly a decade old if not longer. I still recommend it, though.
When this set was released, there were songs that were never released to the public that are included in this set. However, since then, I'M A RAINBOW was finally released and fulfilled the longing need of Donna Summer fans for her early 80s material.
It also includes her song CARRY ON which was released as a dance song that went to the top of the dance charts several years after this set was released.
