Music SOUND weird

Sometimes when I played a song, the volume become small.. thenn loud. But volume button is at max. What happened? This is weird, nothing wrong with the speaker, it's not broken. the sound start acting weird randomly.

What OS do you have? My music seems to stay at one level....
I see you have the newest OS. Did you have these issues before you upgraded the OS? Maybe you need to reload it.
