You might want to try Cesium: http://www.cesium-app.com/

You can hide most images/covers on Cesium. I bought it one or two years ago, use it sometimes instead of the Music.app.

On a side note, one feature I'd wish was in all these players is the ability to pin stuff. I'd like to pin x albums, that's how I listen to them, x albums per month.
