Here's one that Avicii fans (and/or Lana Del Rey fans) were waiting on. As you should know, Avicii's 2013 Ultra Music Festival main stage set wasn't JUST live renditions of his album tracks; he played some fresh tunes in the mix as well. One people had been waiting for was this collaboration (which is either with Lana Del Rey or Audra Mae, apparently), which features her commandeering one of his inspirational tunes in a way only Lana (or Audra) can. Is this an album track? We've no clue. We just have a radio rip of the cut.
