I have a favor. Can you help me?

So, I don't know how to edit any music so.. Can you please edit the song of fluttershy in My little pony: friendship is magic. The song is fluttershy's lullaby. I only want the part when fluttershy sings, can you please edit it and make it 3 minutes long and cut out the part where sweetie belle sings. Also, can you upload somewhere I can download it? PLEASE!!
