Function "strstr ()" is not locating what I expect

#include <stdio.h>
#include <string.h>

char tracks[][80] = {
    "I left my heart in Harvard Med School",
    "Newark, Newark - a wonderful town",
    "Dancing with a Dork",
    "The girl from Iwo Jima",
};

void find_track(char search_for[])
{
    int i;
    for(i = 0; i < 5; i++){
        if(strstr(tracks[i], search_for)){
            printf("Track %i: '%s'\n", i, tracks[i]);
        }
    }
}

int main()
{
    char search_for[80];
    printf("Search for: ");
    fgets(search_for, 80, stdin);
    find_track(search_for);
    return 0;
}
