Parse music.yml so that we can access it in Ruby.
Your parsing code should return an object that allows you to access attributes using the [] operator:
data["genres"].last["artists"].first["albums"].first["tracks"].last["name"] => "But Not For Me"
The returned object should also allow you to access attributes using method calls:
data.genres.last.artists.first.albums.first.tracks.last.name => "But Not For Me"
Bonus points for corresponding test suite and WIP commits to show your thought process.
