This issue only seems to happen with paired speakers/devices, not when playing music through the phone itself.
At the end of every track it repeats a small portion of that track before going straight on to the next track. I have checked lots of settings and it isn't crossfade, as it doesn't repeat the end of the track itself. This has happened on all albums, playlist when paired with my Optimum ears megablast and also when paired to the car sound system - I haven't paired with anything else yet.
I am using Samsung Music version: 18.104.22.168
It is very annoying so I would be grateful for any hints/tips/workarounds.
