Unfortunately, even that doesn't really tell you much. Having SEO is not the same thing as popularity. If a zillion people are complaining about Pro Tools' upgrade price, that will get a lot of SEO. And of course, GarageBand "outsells" any other Mac program because it's bundled with Apple computers.
Also note that the internet popularity chart mixes genres. FL Studio, Ableton Live, Maschine, and to some extent GarageBand are beats-oriented programs. Audition is used more as part of Adobe's Creative Suite. Digital Performer has a strong niche market among video pros who don't want to go the Pro Tools route.
The two stats I can state with
absolute certainty are that Pro Tools is by far the best-selling program called Pro Tools, and Sonar is the best-selling program called Sonar.
