I'm trying to complete the road to fame quest for teen sims and am having a hard time getting past having to write 6 pieces of music. As of now, my sim can play the bass guitar and the keyboard. She has written 5 pieces so far and I am having a hard time getting the last piece. She has gotten 3 in the first row which unlocked the bass guitar. She needs one more in the second row to unlock the drums. I have alternated back and forth between the guitar and keyboard, but the same pieces of music are coming up and I can't get another one to make it 6. I'm close to finishing this quest and there are only 3 days left. I hope I can finish on time but I'm stuck.

Can anyone provide tips or suggestions for this task? Anyone else having the same problem as me?
