I have the same question. I have been using a metronome for everything for quite a while and it still seems like I am not where I should be with my internal clock especially when playing more complicated songs with ghost notes, sixteenth notes mixed in with eight notes, etc. which is common fare in  any song. I just keep plugging along tapping my foot with the beat and hoping it all clicks in at some point. It’s gotten better but man it just ain’t good enough yet.
