Apple Music download files keep corrupting

This problem started a couple days ago for me when I boarded the cruise ship I'm currently on. All the songs that I downloaded from Apple Music no longer play and I get a pop up saying "cannot decode, media maybe be damaged." The ships complimentary Wi-Fi doesn't support media downloads so I can't just redownload everything, it's over 125GB of music anyways. But yesterday I got the chance to use Wi-Fi ashore and I tried to redownload a couple of my fav albums and they were working for around 24 hours before the problem began again. I have a couple albums I uploaded myself to iTunes that play just fine, the problem is only with Apple Music downloads.
