You can load music using the load() method and passing in the music filename. You can then play the music in the background channel using the play() method.
Both of these methods are contained within the music submodule. The only parameter is an int representing the number of times the music will loop. If set to -1,
pygame will loop the music indefinitely.
```Python
pygame.mixer.music.load("music.wav")
pygame.mixer.music.play(-1)
```

Sounds can be stored and played using the mixer module. The module is initialized by default, thuogh you can reinitialize it to change certain settings. A Sound object, when played, will immediately return while the sound continues to play on a certain channel. The channels are usually selected automatically, and the default is 8 simultaneous channels. However, more intensive programs may modify/control how many
channels are available. There is also a submodule called music which is used for music playback and provides a special channel for it.

Sounds in Pygame

Pygame Documentation

You can create a Sound object by using the Sound() constructor method and passing in the sound filename. Pygame will accept both .wav and .mp3 filetypes, but .wav is the most consistent without any glitching or audio lag. 
```Python
death_sound = pygame.mixer.Sound("death.wav")
```
You can then play the sound using the play() method.
```Python
pygame.mixer.Sound.play(death_sound)
```
