I've always loved music and I'll listen to pretty much anything if it's good quality, if I really want to get immersed it will be Puccini but equally happy with anything from The Killers or George Harrison.
It is so evocative in triggering vivid memories almost as good as smells which transcend you back in time at warp speed.
I use a favourites compilation that I add to every now and again on You tube it's a good source for me.
