We'll go with a /10 just because American classic.
This is the song I chose as my fursona's "theme song", both because it portrays his life situation and state of mind quite well. Plus, I have a deep personal connection to this song, and it's a ton of fun to play, and the string bit at the end just pulls at my heart strings because I learned theory on a cello.
Wow, that's really awesome! I love when video games have good music! 9/10
Here's an incredible guitar cover (pretty much exactly the same as the original, just wanted to share this kickass girl with the world) of a song I can safely say I want played at my funeral, and hell, maybe even my wedding. http://www.youtube.com/watch?v=VbE-FPSMEO4
