Apparently not even death could stop Justin Bieber from collaborating with his idol Michael Jackson. The newly released “Slave To The Rhythm” uses a remixed track the King of Pop is said to have finished shortly before his June 2009 death, alongside which the would-be pop icon laid down his own vocals. To intro the new tune — one Perez Hilton has already deemed “the kind of stuff music dreams are made of” — Biebs tweeted black and white shots himself and MJ respectively singing to massive crowds with the words “He set the bar.” (Bieber’s lowering it.) There’s also the following declaration: “MJ. The greatest of all time. #fact” to prove that the Canadian lad does has good taste, if not always the best judgment. Anyway, enjoy.
