Share 'Where do I get cool Music of Christ???... I Tried to....'

I browse my files in my laptop for some cool music to share it with lovers of Christ but all I found was my old collections (I was a Thrash Metal(ist)). Should I erase them? or is it ok to keep them. Can anyone suggest me some links to find related genres...kinda gospel thrash? IDK if i am too naive but I am a very new comer in this new adventure
