SHUFFLE is entirely broken or I've found the limits of how it works.

I have set up a playlist of 2900 songs that I love playing. BUT I dont to listen to them in the order I added them. I want to listen to them all in a random order, and it never to repeat them.

So I use the SHUFFLE option as that would assume you would shuffle the entire playlist.

But it DOESNT, all your shuffle does is choose 100 random songs from the playlist and will ONLY play those songs, so if I go to the end of the queued shuffle songs it then goes back to the first one and doesnt play any of the other 2800 songs in the playlist!!!!!

Trust me I've messed about with it tons of times and it does the same every single time.
The only way to change that 100 songs is to stop the app and then open it again, but then its only the same 100 songs again!!!!!!

Can you let me know how this can be avoided so shuffle does actually shuffle my playlist of 2900 songs!!!!!
