Slow song swapping

[Sterna]

I have MediaMonkey on both PC and android tablet. For some special needs I want to sit in our living room and use my tablet as a remote. PC is situated in our bedroon. So I use WiFi connection and it works fine. I want to play music from my library to my stereos and I cant use cast to because it works only with my TV. So I cast music to my MediaMonkey Player on my PC. My PC has wireless connection to my amp and this way I can make things to work like I want. But swapping songs takes 30-60 seconds and I just can't figure out why? Yes I know that this my MacGyvering sounds strange but otherwise it works fine.

Are the songs you're playing stored on the tablet or are you playing them from the PC via the tablet to the PC?
