What did Australia's music-buying habits in 2013 say about us? The more things change, the more they stay the same.

Despite a digital revolution that for ever changed the music industry (especially for musicians), we still buy mostly American pop songs and albums, a few by British bands (One Direction, Mumford & Sons, Arctic Monkeys), occasionally something European, we can't give up on the classics (Fleetwood Mac, Bee Gees, INXS, Bon Jovi) and we still take the odd Kiwi to heart – then try to claim them as our own.

American musicians dominate sales here, especially solo acts. Perhaps it's no wonder our country artists ape American sounds.

Country music aside, there is a common thread: international pop music that seems familiar wherever you live.

That's why in 2012 Gotye and in 2013 Lorde could reach the pop summit worldwide and that's why we don't care (or even notice) that Avicii is Swedish or that Vance Joy could come from Minneapolis as easily as Melbourne.
