How can i add a MIDI song in my existing Class?

[HelloMe]

My problem is that i have a main menu Class and i want that a MIDI song plays in the background.
I research a bit in the internet but i only found to make a sound class... But i dont want to make a own class for it.

Isn't there a way to play sound a more simple way?

Something like with pictures:

JLabel lblPic = new JLabel(new ImageIcon("C:\\filename\\image.GIF"));

Thank you...
