It would help a lot if you could provide a bit more information about your problem: which instructions did you follow exactly (link?), screenshots of you settings in MU, screenshot of your Advanced Parameters on the Bitmap module in Zooper, which media player app(s) did you test this with and also the versions of android, MU and Zooper you are using.
Hi.. The instructins I followed is from here:
I tested this with Google Music and I got the latest version of MU and Zooper. I'm using the latest 4.3 version of android.
Below are screenshots of MU and Zooper.
