I did catch them. I thought that would be charted to lead since they aren't under or played at the same time as the male vocals.
Still, though, if they're not the lead, they constitute as a harmony part. Take "Subdivisions" for example. The only harmony in that song is a computerized voice going "Subdivisions", and that's not sung at the same time Geddy is singing, yet it is charted in both solo and harmony vocals.
