looks good and works as expected but one suggestion would be to allow the album size to fall below 500 otherwise it doesnt scale down well - the album overlaps with the record image
<element type="Picture" x="5" y="200" width="300" height="300" min="250" max="500" brightness="1.0" ></element>
hopefully that would scale to 500 on your screen but still works when docked to a smaller size
