@mrnakumar thanks for your PR, it looks cool!
I would make 2 suggestions based on the PR.

1. Let's use the standard package embed to load the static file at compile time. Thus we do not need to pass the path argument to load the file at runtime. What you can do is basically create a file in the assets folder and export a var like the below snippet (assets/embed.go)

package assets

import "embed"

//go:embed *
var Assets embed.FS

Then use assets.Assets as the normal file to read the mp3. e.g.

f, err := assets.Assets.Open(filename)
	if err != nil {
		return nil, beep.Format{}, err
	}

2. It would be better to add a command option (--silent) to mute the background music. Afterall, there are some time when people want to play the game without any background sounds.

Please let me know your thoughts.

@liweiyi88 thanks for comments. I have made changes accordingly. Please let me know if this is okay.

@mrnakumar Well done 🎉
