Downloaded music not playing in airplane mode

Currently on iPhone 13 on 15.4.1 and I've been having this problem for a while now. When I fly, and put my phone on airplane mode, half of the songs that I've downloaded won't play. Sometimes the app freezes. I've restarted my phone, redownloaded music, reset my phone. Still having the same problems. I'm starting to get extremely frustrated with this, since I pay for this feature and it hasn't worked properly in over a year. I know that others are having similar problems from reading about it. Any guidance is appreciated.
