For some reason the music that i have on the library only plays for about 10 seconds and then skips to the next track. i checked all the settings and everything looks normal.Can anyone help me?

That is due to another problem known on Z1s and Z2s. You need to look for the Freezing threads in the problem/troublshooting forum. It is related and Pioneer has a fix for it...or so they claim.

Sounds like you are in scan mode.
