Music Notation - Repeat Brackets - How many times?

[NeilES335]

While reading lines of notation in a song or exercise, one is bound to come across a repeat { bracket } at the beginning and end of a line(s) . 

I understand the brackets mean play those lines and at the end go back and play them again, then move on to the next line. Then at the end of the composition there is often another bracket } which means play the whole thing again from the "head"  , the beginning.

What I dont understand is; How do you know how many times to play it through including the repeats? 

For example, while playing the exercise Jam tracks in Learn and Master Session 16, (page 87 and 88 of the lesson book) there are "Repeat { brackets at the beginning and end of all 3 songs.  On the Jam tracks, "Rolling Along"  plays through 2 times;  "A Little Bit Rocky" plays through 3 times; and "Electric Funk " plays through 2 times on the track. 

So by looking at the music notation, there is no mention of how many times to play it.  So, how does the player know? Trying to play along means you have to listen to the tracks first to figure it out.

Did I miss something along the way?

While it doesn't specifically answer my question, this excellent video does discuss many different types of repeat symbols in music notation.

Steve sort of indirectly has always just had us do 1 repeat on any of the LMG series.

on LMG Song Hits Day Tripper in his performance video, Steve repeats twice and moves onto the song. 

When I run the Beatles Day Tripper song.. they repeat 5 times before the verse starts.

guess "your mileage varies"

After reviewing the YT video I see that the songwriter often places a " _ x " (number of times) symbol above the dotted bracket to indicate number of times played. 

Shouldn't this be a "standard" method so the player can just look at the notation and know?

Rolling Along & A Little Bit Rocky - The first part repeats then you play to near the end and repeat the entire song (including the first repeat) to the end. 

Electric Funk - Repeat the first part then continue. Repeat the second part, but you do not start at the beginning.

I have seen the number of times in many songs so it is common. You have to assume some improvisation in each performance.
