yes, I'm referring to windows10 mobile on my lumia 640lte. I don't think the build version makes any difference...its always been like this. I have roughly 160 tracks on this phone, not many by some standards! so when I press shuffle Groove shuffles the tunes, but it only shuffles so much and then it is these shuffled songs that become...the shuffled songs, with slight variations pulled from deeper in the list. I actively delete tracks now and again and upload new tracks in the hope the others will get pulled into the shuffle. but invariably the next new shuffle becomes the...the standard shuffle over and over again - with minor variations. so uploading more tracks to my phone in the hope it would shuffle deeper does not make sense as Groove would only shuffle a small percentage of what's available. thanks for your reply by the way. cheers, drew.
