The way to go with foobar is to download a premade UI you like. Sometimes the installation process is a little convoluted, but nothing compared to customizing its UI yourself from scratch. Back when I used foobar a lot, my go-to UI artist was br3tt on DeviantArt, I don't know if he's still active.

Nowadays I listen to music off my phone, and on that platform BlackPlayer is as close to perfect as a music player gets.
