Comment 3 for bug 1481396

I think anything other than integer value for this would be weird. I don't whether you round to the nearest integer (rounding by 0.5) or just ignore the decimal really makes a huge amount of difference either. In fact I'd lean more towards ignoring the decimal and always rounding down, as then the grouping matches the visual representation and it still performs the function of grouping tracks and removing the areas between BPM where things miss the additional hierarchical sorting orders.
