Local Files from Computer are cut short on Mobile

[felixaitken]

Hi,

I have local files imported on my spotify account on my iMac (legit songs from iTunes). I have synced them to both my Macbook and my iPhone. They are perfectly fine on my laptop but on my phone most songs are less than half the length they should be. They play normally at the start but then suddenly cut off.

How do I solve this?

Thanks
