How to play the synchronized files from deezer app

I have an app (Deezer) which I'm using to play songs. This app when I'm on-line synchronizes the songs that is on my playlist. I know that the file that is synchronized resides in my mobile. I found the path and got the files too. But when I tried to play that file with my default player the file is not playing well (i.e. the sound of the music is not smooth). But when I play the same file with this app it plays well. Is there any way so that I can play these files smoothly with my default player or even after copying these files to my laptop.
