Need some help on using a media server to play songs(Random songs wont play)

Im trying to play songs via media server. I've enabled file sharing on my computer and Im able to see all the songs on my PS4.

Some songs i can play just fine but others will, when i try to play them, switch to a broken file image and not play.

They all work fine on my computer.

Ive tried deleting the media player save file. oddly enough all this does is change which songs will and wont play?

Ive tried using somthing called Plex, which shows up in the media player but says theres no playable media when i try to open the folder. And im pretty sure all the songs are on that media server because they show up in the plex web app.

Any solutions are welcome. I just wanted to do one simple thing but as usual nothing works so im here now.

Thanks.
