You don't already have
from 2001 in your music collection. Otherwise, you'll be wasting your hard-earned money as 29 of the 33 songs here are right off that set, despite adding a few more songs like "Wonderland", & "Goin' to the Bank". Also 2 of the returning songs,"Too Hot Ta Trot" & "Heroes" are presented in their edited, rather than full versions like in Anthology.
For those who don't own Anthology, you'll be getting a great set of music which chronological shows the evolution of the from 1970s funk ("Slippery When Wet", "Brick House", "Fancy Dancer") to a slow jams/soft rock ("Sweet Love", "Easy", "Three Times a Lady") band with a couple of hidden gems in-between like "This is Your Life", "Come Inside", "Jesus is Love" (which has Lionel Richie singing with support from a 40+ member choir) & the Grammy winning "Nightshift".
Once again, I will only recommend this to those who don't already own Anthology
