My Question or Issue

As of yesterday, i can't play any music on my spotify web player.

Message Error : Spotify cannot play this music at the moment.

And when it does play one music, it's only for 2sec, after which there's no sound but the player works.

My Os is too old so i can't get the app either. Please Help me !!!!
