Itunes on a new computer

Usually I can work things out but now I am very frustrated with Apple.

I have a new PC BUT with the old hard drive from the old PC included....this is where ALL my music etc is.

Firstly Itunes on the PC would not see the ipad. I eventually got the PC to sort of see it and sync BUT not in Itunes.

Now I have this ***** apple music program which is supposed to see my music but all I have is podcasts...which I neither watch nor save.

Where the heck is my music....or do I have to buy an Android.

I have reloaded itunes on the Ipad.

I have reloaded Itunes on the PC....but ended up with Apple Music which I DON'T want.

I cannot see the ipad now in "portable devices" on the PC.

AND I am running out of hair.

Hopefully someone can explain.
