20th Century Masters
The Millennium Collection
This was part of the series of CDs that were all called "20th Century Masters". It is a budget-level entry. It only has 12 songs on it. It is missing two of their biggest hits, "Close to You" and "We've Only Just Begun" and has some album tracks on it.
There are a couple of remixes on this album, but it is not one I listen to often. I don't remember when I actually purchased it, but I probably only bought it because I am a completist.
