I agree that this would be a very welcome feature, Musicbee is the best music player by far, but this scrolling problem is pretty annoying. It forces you to hold the "alt" key, thus forcing you to use both hands just to navigate through your music library). And even with the "alt" key pressed, the scrolling speed is kind of fast. Musicbee is known to give its users A LOT of freedom so I don't really get it why not implement an option for this, it shouldn't be too hard, I think. I have no idea.
