r=me, with the most minor of nits. (Don't feel like you have to change the patch though.)

It's not really worth it, but you could do:

auto& tracks = m_trackSet.values();
bool active = std::any_of(tracks.begin(), tracks.end(), [] (Track* track) { return !track->ended(); });

I wish we had those STL algorithms directly on our storage classes so we could do `m_trackSet.values().any_of([](auto track) { return !track->ended(); });`
