How to transfer music from my Iphone to my pc?

Ok so i'm an idiot. I know. But my phone got wet while babysitting and won't charge, it still will brighten up and say that it needs to be charged but it won't turn on anymore… I didn't set up icloud, and i haven't synced my phone to a computer since April… Is there anyway i could get my pictures, music, and contacts back from my computer? Like by using icloud (which i just set up on my pc) to pull all the info off my dead phone?

If your phone is not dead you can try it by turning on the bluetooth and if it is dead than take the iphone charging cable and connect it to the computer i'm sure it will work

You may refer to this step by step guide, it's about how to transfer songs from ipod touch and iphone to computer. It works pretty well for me.
