Nielsen SoundScan’s mid-year report is in, and some of the findings are a little surprising.

Over the past year, digital single sales have dropped 2.3% to 682.2 million units from 698 million units at this same point (through June) in 2012. Surprisingly, while the sales of singles drop, digital album sales continue to rise—despite a drop in overall album sales—increasing 6.3% to 60.8 million sold.
