HTC One M8 Unable to store music on external

[britishmerc1]

So I just got a 32 gb external SD and trying to save my music on it. I've seen the other steps (uninstalling and reinstalling, reformatting, and moving files) and have tried every one and I'm even trying to find the file exstension with no luck. I got into android/data and there is nothing in there with spotify. I've checked internal and SD. I was wondering if i'm missing something or if others are having the same issue. Any help would be appreciated!
