Can’t get rid of whitespace

For the longest ive been struggling with this, tried 100 things, but as an inexperienced/selt taught blogger, Ive ran out of options. When you go to my site, CultureLeak.com, you’ll see every post has a read-more button that says ‘download’
I want to remove the gap between that button and the embed audio players.

The audioplayer seems to be the problem, because on the single posts I have the same problem. I tried using div-style codes for margin, float, block/inline. I tried using my Easy Google Fonts to change the embed player, but I can’t remove the white spaces. Anyone has an idea?
