There are some mistakes, I think, here...
A bar is 4 beats, but in FL Studio, 1 bar is normally 1 whole pattern. Normally, when you listen to music, the best way to get what a bar is is by listening the snare/handclap.
1 bar starts with a kick and got 2 snares/handclaps.
Ex: regular boom bap
Kick - - - Snare - - - Kick - kick - Snare - - -
(in a pattern with 16 buttons) THAT'S 1 bar
In Lyrics...
Normally, a verse is 16 bars and the hook is 8 bars...
You know very well who you are <------------------------------------- 2 bars
Don't let em hold you down, reach for the stars <---------------- 2 bars
You had a go, but not that many <------------------------------------ 2 bars
'cause you're the only one I'll give you good and plenty <------ 2 bars
Another Biggie classic as example...
Biggie Biggie Biggie can't you see <------------------------------ 1 bar
Sometimes your words just hypnotize me <------------------- 1 bar
And I just love your flashy ways <--------------------------------- 1 bar
Guess that's why they broke, and you're so paid (uh) <--- 1 bar
And that part is repeated twice to make it 8 bars...
