While loop hangs during higher output

this is my first First post!

I run a jazz band that has a music book of over 500 tunes. Every gig I create a setlist of about 30 tunes of varying genres. I'm attempting to make a program that creates a randomized setlist for me so that I don't have to spend an hour doing it myself.

Explanation of code:

1. Each tune is an object with a number, title, and genre. These objects are in an array called "master".
2. I filter out each tune into three separate arrays of genres: swings, latins, and bossas.
3. function containsObject(): outputs false if object exists in list and true if object does not exist. This is used to check if a tune already exists in the setlist im creating.
4. swing_func(), latin_func(), and bossa_func() are all the same, and randomly splice tunes from the various genre arrays into the final setlist array. These are all called at the end in make_setlist().

The final setlist cannot have repeating tunes, or repeating genres. The preferred order is swing, latin, bossa, swing, latin, bossa, etc.

Output: 30 (or another number) randomized tunes in swing, latin, bossa order. No tune is repeated.

Problems: So far this code works if I keep the setlist length below 50.

1. Is there a better way to write swing_func(), latin_func(), and bossa_func()? It took me forever to figure this part out.
2. If I make the setlist length too high, the code hangs...

SETLIST LENGTH CODE:

function make_setlist(){
    while (setlist.length < 30) { //if length is too high, it hangs
        swing_func();
        latin_func();
        bossa_func();
    }
}

    {Number: 0, Title: "Amor", Genre: "latin"},
