Try to get a feel for what each BPM you're interested in playing sounds like. A quick way to do this is to open the map in editor and let Auto play a stream for you.
Once you know what an accurate stream of that BPM sounds like it's just a matter of attempting to imitate that over and over until it becomes a habit.
