i had music in itunes but i dont know how to put on my new iphone.

Not sure what your question is.

The topic asks how to put music on an iphone.

Your post asks where your music is.

Which is it?

Your music is wherever you put it.

You sync it from itunes on your computer to your iphone.

I have bought music through the years and I need to down load it on my ipod

See:
