The media player is so large because it is a video player, so just bear that in mind, this hack assumes that there is an audio file attached. I don't have a full solution. Here is my doodling with it.
The shape of the media player is determined by the size of the iframe it plays in. The default height is 14.5rem, you can change this to 50px and squash the box
You have to 'not show' the 'music' image. The <video> tag has an audio-player class. you can set the background-image attribute to "" or delete the attribute.
You can bring the player into the smaller frame by adding these attributes to the <div.dVRGv_crZr> the player lives in
{
top: 0px;
margin-top: 5px;
}
I end up with

Once you collect all the css changes into a file you can add this css to the theme of a subaccount. Again this will alter/clobber all the video players in that subaccount, so you have to be sure you won't be breaking other things.
If you want a mini-media player you'll probably have to run it through the canvas ideas process.
Hope this helps
