Twenty One Pilots reached a milestone this week when all 14 songs on their 2015 album Blurryface were certified gold or platinum. The RIAA made the announcement yesterday. It’s believed to be the first time this has ever happened, at least since the start of the digital music era. Many of the songs were boosted by the addition of streaming data into sales figures in 2016. Gold status means 500,000 copies sold in the U.S. Platinum is one million. Blurryface is certified triple platinum with over 3 million copies sold.
