Fix this kind of bug/cheat during the game pls.

Hi guys! Maybe you already know this kind of trick during  the game, in order for you to win in PvP you must to correctly guess the song right? The faster you click, the higher the score right? There are five songs which determine your scores but sometimes when i'm in the middle of my game and hesitate to my answer, you know what i did? I listen to the song first then after that i'll refresh the game and when i came back the game, it started to the song before i refreshed the game then easily clicking the right answer for that song and win!. Yeah this seems cheating and unfair to other players. Please fix this kind of bug during the game.Thank you.
