When is 13 a lucky number? When it’s the number of years it’s taken for the music industry to post its first yearly increase in global recorded music sales, which is what happened in 2012, according to new figures from the International Federation for the Phonographic Industry.
The group’s annual Digital Music Report, issued Tuesday in London, noted that overall music sales rose from $16.2 billion to $16.5 billion, or 0.3 percent, from 2011 to 2012, the first time in 13 years that worldwide sales didn’t decline.
