Rush #21 of Rock's Richest 50

The April 3rd issue of Rolling Stone contains the story "Rock's 50 Richest". The tallies are based on the year 2002, and Rush came in at #21, with touring net at $13.4 million. However, revenue from recording is listed as $0; shouldn't this total reflect sales of Vapor Trails?

"Rush released their first new album in six years, Vapor Trails, and followed it up with a tour that brought the Canadian power trio an $18 million guarantee. The band's devoted following helped the outing gross $27 million in sixty-two cities. But that's a lot of moving around - compare it to Billy Joel and Elton John's tour, which grossed $65 million for thirty-four shows in fourteen cities - so a good chunk of that got eaten up on the road." - RollingStone.com, Apr. 3, 2003 issue
