Studio Quality formats are already widely available for some of the U.S.’s most popular music of all time:
77% of RIAA’s 100 Highest Gold & Platinum Certified Albums
79% of one major streaming service’s Top 100 All-Time Streamed Tracks
78% of the SoundScan’s Top 100 Albums of 2018
68% of one major streaming service’s Top Weekly Tracks

真是令人振奮啊！
