@Isaaaaaak - I think it's also due to the fact that it's one of their most widely-available albums. If a music store had a Stranglers section in my experience, guaranteed they'd have Greatest Hits, The Collection, the Epic Years, or the UA Singles before they'd have studio albums. As a fan, I obviously agree people are seriously missing out if they don't move on to the other stuff, but I can understand why it happens.
"Friends? We weren't friends with anyone!" - JJ Burnel, front man of the great The Stranglers, reminisces about Joe Strummer, "sharing a flat with a bloke called Wilko Johnson," and the tragic story behind "5 Minutes." Burnel also discusses the punk band's songwriting evolution, and their seventeenth (seventeenth!) studio album, Giants: http://www.songfacts.com/blog/interviews/jj_burnel_of_the_stranglers/
