I started playing about 5 months ago, and I figure that the best approach for progression is to incrementally increase the piece's difficulty. I was doing that for a while until (last week) I decided to go back a bit and learn the song Apologize. My favorite genre are those songs which are both climatic yet melancholy.
Here's a link to the most difficult song I can play now:
Now I'm obviously looking for something that has a similar feeling that it instills, but is notably harder.
Ideas?
