Can't play local files on iPhone, stuck on Waiting to download

[Okaa]

So yea, I'm posting this (yet another) topic because I can't play my local files on my iPhone. I used a mac as the computer and an iPhone 5s as the mobile.

I've tried doing everything. It just stays at waiting to download

-Deleting stuff to get more storage

-Deleting Spotify and re-installing on both iphone and mac

-Using a different Wi-Fi

-Connected my phone to the mac with a USB

-Updated spotify and the system on both iphone anc mac to the newest

-adding and deleting songs from a playlist, toggling offline mode download on and off, adding the local songs to one song per its own playlist

-Disabled my firewall and VPN protection.

Basically everything, and I don't know why this is happening now, because I did this like a week ago and it worked, and now as i tried to add new songs, it didn't work. I'd really like some help. Thanks.
