This program helps you in your gaming activities on your computer.

For example if you are playing a fps in multiplayer, or even single player
and you have a mp3 player opened playing a melody you don't like, you
will have to switch tasking with "alt-tab" key combination , or "ctr-esc"...,
with the risk of getting your system blocked...

So isn't easier with
GamerMp3PLayer, when you press a key and you change the music with out
quitting game?
