I think when you start out with death metal a lot of things sound like "noise." Even after I had been into death metal for a while, there were some albums I had that sounded that way to me. I was away from them for a while, listening to classical, jazz, prog, etc. and I came back recently and the "noise" came apart and I could hear what was going on and how great it was.
One of my first death metal albums was Vader - Litany. They have a pretty simple style, so I think it's good to get into.
For melo-death, I have to recommend 'Rusted Angel' by Darkane. I absolutely love that album. Listen to the title track, it will simply blow you away.
