Digital music sales in Japan fell 3% in value in the first six months of this year, compared to the first half of 2009. That’s according to figures released by industry body RIAJ, showing revenues of 43.4 billion yen ($512.2 million) for 1H10. In terms of digital units, the fall was 5% to 222.4 million. A slump in mobile sales were the main cause – down 6% in units and 3% in value. Internet downloads were up 2% in units and 3% in value year-on-year, but still make up a minority of the market. Splitting out those mobile figures, ringtones were down 17% in revenue, while ringback tones grew 4% and full-tracks were up just 1%.
