TuneCore says its artists have earned $330 million the company launched in 2006.
The numbers were garnered from more than 4 billion cumulative streams and download units, according to Billboard.
Artist earnings grew 20% in the January-September 2013 period year-on-year, and TuneCore artists saw a 135% increase in music downloads and streams over the same timeframe.
A string of new product and service enhancements launched in recent months played a part in the spike, the company notes.
Store partnerships including Gracenote and Shazam, along with JUKE and 7digital international streaming services, are also “providing (artists) even greater worldwide music exposure and opportunities to grow their music revenue.”
