Not a bad collection of tracks, but as best-ofs go it's not exactly life-changing. Perhaps a good buy if you're new to Joy Division, or only want to buy one album and just have to have Love Will Tear Us Apart.
Most of the popular classics are on here, but personally I'm disappointed New Dawn Fades, Warsaw and The Eternal/Decades weren't included over, say, The Only Mistake or Something Must Break. However, the obvious Atmosphere, Transmission, She's Lost Control, Shadowplay and the ubiquitous aforementioned LWTUA are always nice to hear.
Personally, this is the last JD CD I've bought to complete my collection and it's almost entirely superfluous. The "Permanent Mix" of Love Will Tear Us Apart isn't great.
If You're interested in starting a JD collection, you'd do better starting with Unknown Pleasures, then getting Closer, Substance, Still and the Warsaw album, then all the other bits and bobs. That's my preferred order.
