NavigationView {
  VStack(spacing: 0.0) {
}

.navigationViewStyle(StackNavigationViewStyle())

  FeaturedCats(artists: mix.tracks.map(\.artist))
    .padding(.vertical)
    .background(Color.gray.opacity(0.2))
}
.navigationBarHidden(true)

List(mix.tracks) { track in
  NavigationLink(
    destination: DetailView(track: track),
    label: {
      TrackRow(track: track)
    })
}

@State private var showMessage = false

.onTapGesture {
  showMessage = true
}

.popover(isPresented: $showMessage, content: {
  MessagePopover()
})
