попробуйте следующее решение:
Для каждого альбома, как я создаю ItemsControl для своего списка конкретные песни .

Объяснение:
Основная идея второй части вашего вопроса - использовать какую-то агрегацию событий.
Как это выглядит 
С уважением.
Спасибо за ваш ответ! BaseObservableObject не найден. Есть идеи? Можете ли вы выслать мне папку с проектом? – Rotem
@RotemSimchi, пожалуйста, просмотрите обновления, я добавил BaseObservableObject. – Ilan
Спасибо! Оно работает:). У меня последний вопрос: когда я с мышью на альбоме, вокруг него синяя квадрат, есть способ удалить его? ссылка на изображение: http://i.imgur.com/Bt9lmoN.png – Rotem
