Shuffle on connect to other device

[bab2]

Hello,

I've got some questions about the shuffle play when I control my actual song on my computer from my computer. I've got a big playlist (+500 songs) and i like to control the music from my phone. But the shuffle purposed by my phone when I choose song to another device is not really a shuffle. One time I've played only 40 song choose one special son and start again the shuffle but the songs who was played was exactly the same that the previous shuffle so my question why doesn't let the the phone control the shuffle like we played on the phone, why use a not random and make a standard queue list when we control from another device ? The shuffle when I'm listening from my phone work, when I'm listenig from my computer it work too but when I control from my phone to my computer not. If I can have just an explanation or just a suggestion about a solution or something like that ^^

Thanks for the read because it was a long post. And sorry for my english if you think he is bad I'm from France.
