how do I shuffle my songs on my iphone following the update?

Basically since update 8.4 I can't shuffle songs anymore Not sure why they decided to screw this up but then nothing suprises me with the twits behind things like lets give everryone free U2 albums and "oh yeah we own all your digital music when you snuff it" I go to Siri and tell it to shuffle playlist - first it says no such command, then it trys to dial random people and then it finally says ok "shuffling playlist" and then it proceeds to pick a song at random (result!!) and hen play it repeatedly (***!!!?)

Can any one assist?

Cheers
