There are 1,663,200 different arrangements of songs.

I am assuming there is a typo and you just meant 7 out of 11 (I have seen typos like this before). If not, just follow the same steps with 77 out of 11. However, you will have a very high number.

All we do is start at 11 and count down 7 spots, then multiply.

11 x 10 x 9 x 8 x 7 x 6 x 5 = 1,663,200
