If we had optional ratings given at the end of an award, you can see more about the track. Don't you already begin to start having ideas of which of those tracks you would prefer to try? It may not be the on with the most award or most stars, although in that example, you would most likely want to see Track4.
Compare that to the first list and you would have no idea Track4 is worth seeing at least as much as Track5 or Track6, unless you knew the authors.
Now maybe track4 is by an author you never heard of, now you really see some benefits of ratings, they can show you a direction you not have followed before.
