In reply to dustin.

But the original is being counted on Billboard, not the remix.
Don't get it twisted sweetie.
And Japan is currently the biggest market according to IFPI. US is second and dwindling, many are predicting it will be overtaken by Germany in a couple of years. Miley is unknown outside of the US whereas Lana is huge worldwide, especially in Europe.
Summertime Sadness out peaked Ooh La La (which had a Clear Channel deal, more promo than Lana has had in the states since the release week of BTD) and Criminal.
Anyways back to Miley. We Can't Twerk only went top 10 in 6 countries (5 Anglophone, the definition of local) and it's her most successful worldwide single to date. Summertime Sadness did better with it's original European release last summer.
Miley is local, and Methney is a has been. The end.
