Songs won't sync

[superqueen15]

So it's that time again when spotify is taking up a **bleep** ton of space from my phone so in order to get it to go down again, I need to delete it and reinstall it. So, I delete it, reinstall it, make sure all my local files are on the PC I'm currently using and click 'download' on the playlist but nothing happens. It's not downloading my local files on my phone and I have no idea why. It's not even stuck on 'downloading' it just says 'downloaded' when it hasn't downloaded **bleep** (excuse my language). I have the songs I want to sync on my laptop, I've made sure they're in the correct playlist, I even re-downloaded ALL of the songs JUST to make sure I wasn't making any mistakes. What am I supposed to do?
