It's worked fine before! I've never had this issue until now. My local files will not play on my mobile phone, no matter what I do and how hard I try. Local files that I had downloaded before worked fine, and then I went and cleared the cache on my phone and uninstalled and reinstalled Spotify to see if that would help, yet it only made it worse. Now all of my local files are not playing. I've rebooted my phone. I've checked my WiFi.

The tracks play fine on my laptop. They're MP3 files, so it has nothing to do with iTunes or anything like that. All mentions of this problem on other threads are from last year. I've tried all that's been suggested. Please help!
