Eponymous is an album I put off buying until I could find it in the cheap-o bins. If you own all of R.E.M.'s albums from their IRS years, this compilation is highly unnecessary. At most there'll be two songs on it that you don't have (one is an alternate version and the other is from a soundtrack). So yeah, Eponymous gets more and more unnecessary as other R.E.M. compilations spanning their entire career emerge.
