Sure, I can help you with that. Here are some troubleshooting tips if your Spotify playlist is not playing:

1. **Check your internet connection**: Spotify requires a stable internet connection to stream music. If you're using mobile data, try switching to Wi-Fi. If you're on Wi-Fi, try restarting your router.

2. **Restart your device**: Sometimes, a simple restart can solve many issues. Close the Spotify app and restart your device. Once your device is back on, open Spotify and try playing your playlist again.

3. **Update the Spotify app**: Make sure you're using the latest version of the Spotify app. Go to your device's app store to check for any updates.

4. **Log out and log back in**: Try logging out of the Spotify app and then logging back in. This can often refresh your account and solve any minor issues.

5. **Reinstall the Spotify app**: If none of the above steps work, try uninstalling and then reinstalling the Spotify app. This can often solve any major issues by giving you a fresh start.

Remember, if you're using Spotify on a computer, you might also need to check your computer's sound settings and make sure your speakers or headphones are working properly.

If you're still having problems after trying these steps, you might want to reach out to Spotify's customer support for further assistance.
