Leaderboard Scrolling

We should be able to look through the leaderboards at various people's scores, not just those who have scores similar to our own. Also, the ability to sort songs based on rankings, that way, lets say I'm in the top 10 for every single song... Except for 5 songs where I rank in the top 20. Rather than scrolling through every single song to figure out which ones are my worst, I can just sort the songs and have all of my worst ranking songs immediately available to me so I can focus on improving their scores.
