fgets printing two lines before input

fgets printing two lines before input

So I am trying to write a program that will let me read a user input for
data on an MP3 file using a doubly linked list data structure. I got most
of the methods and functions to work, but when I am prompting the user to
put in input it prints out two lines before the user can input for the
first line. So for example
int main()
{
int user_input = 0;
while(!(user_input >= 4))
{
struct MP3_data_node* MP3_data;
MP3_data = (struct MP3_data_node*)malloc(sizeof(struct
MP3_data_node));
printf("\nPlease select a number for one of the following
instructions:\n");
printf("0: add to list\n1: delete from list\n2: print the list
from beginning to end\n3: print the list from end to
beginning\n4: exit\n");
scanf("%d", &user_input);
if(user_input == 0)
{
printf("Please provide the artist:");
fgets(MP3_data->artist,50,stdin);
printf("Please provide the album:");
fgets(MP3_data->artist,50,stdin);
printf("Please provide the song title:");
fgets(MP3_data->artist,50,stdin);
printf("Please provide the year the song was released:
");
scanf("%d", &MP3_data->yearReleased);
printf("Please provide the length of the song in
seconds: ");
scanf("%d", &MP3_data->runTime);
addToList(MP3_data);
}
...
So it prints out "Please provide the artist:Please provide the album:" and
then let's me put the input in, so my question is how do I make it so that
it prints: Please provide the artist: (user input) Please provide the
album: (user input) etc.
