App problems?

The app is skipping, buffering, and restarting the whole app all of a sudden. This started happening yesterday. I cleared app cache, restarted my phone, deleted files, and freed storage, but nothing will work. It doesn't matter which song it is, it just gives me a hard time. I also checked my data; it's fine. Same with my wifi. All of it is full bars— no problems.

It did this with my old phone before it broke. I've only had this phone for a year now. Brand new.

Do I uninstall the app and reinstall it? Will my liked songs be deleted?
