mp3/ogg player

[Francis Lavoie]

Hi

I looking to build a second program in python. I would like to code a 
music player, which can play mp3 an ogg files. But every solution that I 
find, seem over complicated or not multiplaform.
Is there a simple package of libraries that we only have to install 
once, or plug it into the program that give mp3 and ogg playability like 
a .jar file in java?

My main developpement OS is windows for now.

Thank you
