For whatever reason, I was thinking about U2's Pop the other day. You may recall that people aren't too fond of that particular record. The pinnacle of their let's-drown-in-irony shtick, some say. The album they rushed to finish in time for their upcoming world tour, historians note. All true, but I still have a fondness for a few of its songs -- like "Discotheque," the lead track and first single. How can you resist the Edge in a shiny shirt?
