That's pretty strange. Could you share the links to the songs on this thread? So if you could click on three dots at end of song and choose share option. I've shown how to do it here in this attachment. I'll check to see if I can play those songs on my desktop app. I should be able to play the songs. What you could try is a clean reinstall of the Spotify app on your desktop and phone if you have not already. If it hasn't resolved then please post in this thread again.
