Good morning AkulaUA,
It sounds like you’re having trouble playing your songs the way you want because the songs are only shuffling. I’ll be happy to help out.
When you toggle shuffle off, the songs should play in order. Take a look at these steps to make sure that shuffle is turned off: Play, repeat, and shuffle music - Apple Support
If you’re still noticing songs playing on shuffle even when it’s toggled off, let us know a few more details. Are you an Apple Music subscriber? Does this happen when playing songs in a playlist? If so, does it happen with all playlists?
Cheers!
