Hey Everyone

could somebody help me out... Ive been a spotify customer now for years and this is the first time something has confused me... I drive a lot and I have a load of playlists that I have lovingly put together with a load of my fave albums on, I download these so I dont use my data and I normally sort them by artist and listen alphabetically...

for some reason earlier i was listerning to a playlist and everything was fine, after listerning to my release radar and then going back to my playlist I have found that all of my albums have now been mixed up, it is still listed by artist alphabeticallly but the albums are no longer playing in the order they are meant to the tracklisting is all messed up, I think it is playing alphabetically

does anybody know why this has happened... on my laptop everything is fine only on my phone is is playing up? i'm tempted to re install it
