According to this report, Apple is wisely (and perhaps proudly) submitting iTunes sales data to SoundScan, giving an added burst of legitimacy to its numbers.
When I was younger I used to consider buying some of my CDs intentionally at larger stores where sales were being reported to SoundScan. Let my indie voice be heard! So I’m spending my $15 at Sam Goody—at least the world will know I’m buying the new Odds record. BBC Records will understand.
SoundScan has been tracking online music sales for a while, so this news isn’t a big stretch. But it is good news.
