iTunes playback error on iPhone

When listening to a particular song via my phone, it resets to the start of the song at several points in the song and it isn't possible to listen to the whole song. The same song is perfectly fine listening through my iMac.

It's driving me mad, any help would be hugely appreciated. I've tried un-syncing music and also logging out of media and purchases (as recommended on a separate post about a similar playback issue... neither have worked for me)

Thanks a lot
