Gotye's extraordinary 2012 just keeps getting more extraordinary. 'Somebody That I Used to Know,' the hot Aussie export's crossover smash featuring New Zealander Kimbracontinues its assault of the Billboard charts, racking up its fourth week atop the Hot 100 and its tenth at No. 1 on the Alternative tally.

Not only that, this week the tune also reaches the apex of the Dance Club Songs and Dance/Mix Show Airplay charts -- thanks to remixes from the likes of Thin Red Men and Tiësto -- making Gotye the first artist ever to top all four in the same week. It also remains at No. 1 on several other Billboard charts, including its third straight week on Hot Digital Songs and as the top Airplay Gainer on the Hot 100. It also racks up its fourth consecutive week at No. 1 on the On-Demand Songs survey.

Meanwhile, for a piece of the bigger picture, Time magazine examines 'Somebody' as it "joins the annals of biggest breakup anthems of all time" and asks "how does it measure up to its contemporaries?" So, how does it measure up? According to Time, pretty well.

The article puts 'Somebody' in a point-rating showdown against Kelly Clarkson's 'Since U Been Gone' and Adele's 'Someone Like You' -- both massive hits with staying power, commercially and emotionally -- and determines Gotye's tune holds its own. Not bad for a little indie ditty from an Aussie rocker pretty much nobody had heard of a year ago.
