I made a transparent version of the new release candidate. I probably can't keep up with the updates so here's the xml codes that you need to put to get the same results. Also make matte_widget_bg transparent

appwidget_4x1_now_playing.xml

Code:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout android:orientation="vertical" android:id="@id/now_playing" android:layout_width="fill_parent" android:layout_height="wrap_content"
  xmlns:android="http://schemas.android.com/apk/res/android">
    <TextView android:textSize="14.0dip" android:typeface="normal" android:textStyle="bold" android:textColor="#ffffffff" android:ellipsize="marquee" android:gravity="center_horizontal" android:id="@id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:singleLine="true" />
