Yep, besides, by the definition on the graph their own examples of Kate Bush's "Running up that hill" and Metallica's "Master of Puppets" would not count as "catalog" and counts as 'new music' while The Weekend's "Blinding Lights" counts as 'catalogue' music (i.e. 'old' music in the context of this article). Seems overly simplistic to me! It's also worth accounting for how music is consumed and how this is accounted for - i.e. I assume the shift to streaming platforms would naturally cause reporting of old-listens to increase (i.e. if you buy a CD once in 2015 and listen to it every year, this would be recorded as a single 'non-catalogue' sale, while in the streaming world it would be classified as 'two non-catalogue listens and then five catalogue listens'), so I assume more people streaming would drive more 'recorded' catalogue listens unless this is carefully adjusted for.
