Saytda musiqinin nizamsız (shuffle) oxunması – MP3 Shuffle playlist

Salamlar, Actionscript-də pleylist var, lakin istəyirəm ki, mahnılar nizamsız olaraq ardıcıl olmadan oxunsun, yəni next düyməsini basdıqda sonrakı yox, hər hansı bir mahnı gəlsin, kod isə belədir:

Bilən varmı, hansı hissədə nə dəyişiklik etməliyəm? Bir çox forumlarda sual verdim, dolayı yolla izah etdilər, anlamadım.

Bilən olmasa belə, mənə bunu harda düzətməyi məsləhət görə bilərsiniz? Yəni agentlik, developer və s.

Öncədən hamıya təşəkkürlər.
