TTWE however does sound a lil' different from TTWE (Remix), especially the first half.
Do you think Billboard can put them to chart apart? You know how they can be sometimes. Could they take the heat from three different big and huge stanbases?
NO WAY IN HELL
ASK BILLBOARD:
"The case of 'S&M' isn't the last such a late-in-the-game guest artist remix that we'll see, either; a remix of Spears' 'Till the World Ends' - sporting Ke$ha and Nicki Minaj - arrives next week."
Yeah, I was honestly disappointed that the song wasn't more different. The melody/structure after the first minute or so is pretty much identical aside from the new dance breakdown. But I guess it's good that it's not too different then.
