C/C++ :: Shuffle Songs Into Random Order

What's wrong with my shuffle function? It shuffles some songs, yet completely gets rid of others.

Here's the code:

void shuffle() //Shuffles songs into a random order. {
Music temp, temp2; //Temporary music file holders, 'Music' is a struct with string title;, string artist;, and int size;.
unsigned int currentTime = (unsigned)time(0);
srand(currentTime);
for (int i = 0; i < NUM_SONGS; i++)

[Code] .....

I want it to output this:

1. Title: Runaway2, Artist: Bon Jovi2, 2 MB
2. Title: Runaway5, Artist: Bon Jovi5, 5 MB
3. Title: Runaway1, Artist: Bon Jovi1, 2 MB
4. Title: Runaway4, Artist: Bon Jovi4, 1 MB
5. Title: Runaway7, Artist: Bon Jovi7, 5 MB
6. Title: Runaway6, Artist: Bon Jovi6, 5 MB
7. Title: Runaway3, Artist: Bon Jovi3, 5 MB
8. Title: Runaway8, Artist: Bon Jovi8, 1 MB

Or something along those lines, but instead I get something like this:

1. Title: Runaway7, Artist: Bon Jovi7, 1 MB
2. Title: Runaway2, Artist: Bon Jovi2, 2 MB
3. Title: Empty, Artist: Empty, 1856312448 MB
4. Title: Runaway4, Artist: Bon Jovi4, 1 MB
5. Title: Runaway5, Artist: Bon Jovi5, 5 MB
6. Title: Empty, Artist: Empty, 0 MB
7. Title: Runaway7, Artist: Bon Jovi7, 1 MB
8. Title: Empty, Artist: Empty, 1856312448 MB
