Music streamers, say hello to "Back In Black." AC/DC's music is finally available to stream through subscription-based digital music services. The band's music was posted on Spotify and Rdio on Tuesday. Anonymous sources close to the band told the New York Times, which first broke the news, that the Australian band's music could also be available on Apple Music as early as Tuesday, too.

AC/DC has long been hesistant in releasing its music digitally and waited until 2012 to allow its music to be sold on iTunes. "Rock or Bust," the band's latest album, released in November, was its first to be released digitally. Many of AC/DC's contemporaries, like Metallica and Led Zepplin, have already joined the digital age. Metallica's music has been available for purchase on iTunes since 2006 and for streaming since 2012, and Led Zepplin's since 2007 and 2013, respectively.

AC/DC's decision to release its music on streaming platforms arrives right as Apple plans on launching Apple Music. Scheduled to be released late Tuesday morning, Apple Music will also feature music from Taylor Swift and Beats co-founded Dr. Dre, making this the first time listeners will be able to stream the rapper's album "The Chronic." We'll have to wait until 11 a.m. to see if AC/DC has also come onboard Apple Music.

UPDATE: It appears AC/DC's move to streaming is wide-spread. The band is confirmed on Google Play, as of today:
