Hello,
When a music file is open in lightbox on a mobile device (tested iOS7) it is difficult to press play. When you click anywhere on the lightbox content holder the next/prev arrow is selected.
I think this could be fixed by adjusting the z-index of the contents.
Please test from your inspire demo to see the issue:

Thank you.
