Find the number of choices he has for the first song; then find the number he has for the second; then the third, fourth, and fifth.

Multiply those numbers of choices together to find the number of lineups of 5 of the 7 songs.

first song: 7 choices
second: 6 choices
...

Total number of lineups of 5 of the 7 songs: 7*6*....= ___ (you finish)
